TV Antenna Installation Bondi – 15ft Mast

15ft Mast Installation Bondi - Antenna

Today, we are looking at a fairly straightforward TV Antenna Installation in Bondi, using a 15 foot guyed mast. The customer previously had their old TV antenna guyed mast rust out and subsequently fall onto their roof. Thankfully it didn’t do any significant damage to the roof, however, it is a good warning to those of you who have a rusted mast on top of your rooftop!

Before Installation

15ft Mast Installation Bondi - Before

All masts and mounts are normally exposed to the elements. Particularly in areas that are close to saltwater, there is damage to masts and mounts that results in rusting of equipment. As a general rule, large masts like this one (or larger) should be checked every 12-24 months, as rusting can sometimes result in catastrophic outcomes.

Thankfully, in this case, whilst the 15 foot mast fell over, there was no significant damage to the customer’s roof. However, in the past, we have seen mast swing off rooftops and into windows below, or sometimes even hit cars or other objects next to the house.

Our customer was lucky in this case, and we were able to install a brand new shiny 15 foot mast with a VHF antenna directed straight to the Artarmon transmitter.

TV Antenna Sydney

TV Antenna Sydney

It should come as no surprise that the most important piece of equipment in any TV antenna system is the TV Antenna itself! In our guide outlining the 10 Steps to Perfect TV Reception in Sydney, it is the first step listed in order for you to get your TV back to picture perfect.

What Frequency Band - VHF, UHF or Combination?

All antennas are ‘cut’ or tuned for different frequencies. You can get antennas that are used for enhancing 3G or 4G mobile phone reception, antennas for FM or DAB radio, GPS antennas and of course TV antennas. Each of those types of signals are all broadcast on different frequencies. 

VHF (very high frequency) bands, which are from 30 to 300 megahertz (MHz), are used for TV signals to be broadcast on the main transmission towers in Sydney, which are located in Artarmon.

UHF (ultra high frequency) bands, which are a large range between 300 megahertz (MHz) and 3 gigahertz (GHz), are also used for TV signals in Sydney, however, these are broadcast (sent) from different transmission towers that are located in hard-to-reach areas. Basically, wherever the main VHF TV signals cannot reach, the Government has kindly organised for new transmissions on other towers to make sure everyone in Sydney can still get a reliable TV signal. The location of these UHF towers in Sydney are as follows:

  • Kings Cross servicing Kings Cross, Sydney CBD and Eastern Suburbs
  • Manly servicing Manly and Mosman
  • Razorback Range servicing South West Sydney
  • Kurrajong Heights servicing the North West Sydney
  • Bouddi servicing Bouddi
  • Woronora servicing Woronora
If you are close to one of these areas, then you might get a better incoming TV signal on UHF rather than VHF frequency bands. This should always be tested onsite, however, the Australian Government’s MySwitch website may provide some assistance in determining what is right for you.

From there it is simple, if the best TV signal in your local area is broadcast on VHF frequencies, buy a VHF antenna. If the best signal is on UHF frequencies, buy a UHF antenna.

Oh and just to cover them off, combination antennas are antennas that receive both VHF and UHF frequencies. They are often used by installers who do not know how TV signals work and so they can be used in a wider range of situations to ‘guess’ which direction the signal comes from. There are only a few rare scenarios in which a combination TV antenna should be used, and quite often they result in a poor quality signal, can introduce interference into your TV antenna system and cause other issues. Overall, they are more harm than good. 

Low Gain or High Gain?

A TV Antennas ‘gain’ or ‘power gain’ describes how well the antenna converts radio waves arriving from a specified direction into electrical power. This is very important to introduce a strong signal power straight off the antenna. Sometimes, if a high gain antenna is used over a low gain antenna, there can be enough signal power straight off the antenna to avoid needing to install other devices, like a TV Antenna Booster or other amplification devices.

It is often the case that antennas with only very few elements (arms) will be low gain, and high gain antennas will have many elements (up to 18 elements for a very high gain VHF antenna). A top quality high gain antenna should deliver you a minimum of 10db gain (on VHF) and some will get you 14db gain or greater!

UHF Antennas - Yagi or Phased Array?

UHF Antennas generally come in 2 shapes, being a Yagi or Phased Array. A yagi is the more traditional long, narrow antenna (used for VHF antennas), whilst a phased array TV antenna looks like a square mesh board with diagonal metal patterns.

A yagi antenna should be your go-to UHF antenna under normal circumstances. It will provide higher gain and a better quality signal under circumstances where your line of sight (LOS) to the transmission tower is relatively clear.

If the LOS from your rooftop to the transmission tower is terrible, and there are a lot of hills and valleys along the way, then your best bet may be to install a UHF phased array TV antenna. These antennas are better at picking up ‘scattered’ signals which become scattered due to the radio waves bouncing off hills, trees, bushes, and other objects before they get to your rooftop. Yagi antennas are a higher cost antenna than yagi antennas, so you are best to have a signal survey from your rooftop to determine which is the best in your local area.

Front to Back Ratio

The Front to Back Ratio of any antenna is the ratio of the signal power received from the front of the antenna compared to the signal power received in the opposite direction.

Whilst some may not look like it, antennas have a front and a back and it is crucially important that you do not turn them around 180 degrees to have them facing the opposite direction. However, if you were to do so, and you had a bad antenna with a low front to back ratio, there is a very slim chance it might still work for you! 

However, the best TV antennas will have a high front to back ratio, and this is why. If an antenna can receive a signal from the wrong direction, it will introduce ‘noise’ and unwanted signals into your TV antenna system. Because we know that we only want signal coming from the TV transmission tower, we ideally want to completely block out as much other noise as possible. A high front to back ratio will mean that we get lots of good TV signal from the front, and minimal unwanted radiowaves from the back.

Built-in Filters

Depending on your location and proximity to telecommunications towers, you may suffer from strong 4G (LTE) mobile phone signals in your area. Whilst this might be great for making mobile phone calls and watching 4K movies on your iPhone, unfortunately, this can result in interference to your TV antenna signals.

There are a number of stages in which you can ‘filter’ out the unwanted 4G signals. You can have an in-line 4G filter (separate device), a 4G filter built in to your TV antenna booster, or you can eliminate the 4G signal at the source and buy an antenna that has a 4G filter built-in. Note that in some cases, you may require more than one device to filter the 4G signal as it can be very strong in some areas and cause a lot of interference issues for your TV signal.

In summary, there are a number of different attributes that you should look out for when selecting a TV antenna in Sydney. No matter which attributes you decide, there is also the build quality that you should definitely take into account. Australian made TV antennas are generally made out of higher grade aluminium, as compared to some international antennas, and have a more rigid construction. You can rest assured knowing that they are designed and made for Australian frequencies and Australia’s harsh and varying climate. It’s for this reason that many Aussie made antennas come with a 25 year warranty… they are built to last!

10 Steps To A Perfect Digital TV Antenna Installation in Sydney

10 Steps to Perfect TV Reception in Sydney

So the Free To Air TV reception at your house in Sydney has suddenly gone bad. The picture has started pixelating, it then skips a frame every now and then, and the audio is constantly breaking up. There is something wrong with your TV antenna system.

10 Steps to A Perfect Digital TV Antenna Installation in Sydney

In order to get your digital TV reception back up and running again, there are the following 10 steps you need for your digital TV antenna installation in Sydney to get that picture and audio back to perfect again.

1. The Right TV Antenna

The most important part of any residential TV antenna system is the TV antenna itself. If you are based in Sydney, you will need to check whether or not you need a VHF (Very High Frequency) or UHF (Ultra High Frequency) antenna. This will depend on which TV transmitter gives the best signal in your local area. For a large part of Sydney, this will mean getting a VHF antenna and pointing it towards Artarmon in Sydney’s North. But if you are on the outskirts, or in a hilly area, there may be a different TV transmitter that provides better reception.

In addition, no matter if you pointing at a VHF or UHF transmitter, there are many different designs and sizes of antenna that will receive the signal better than others. For TV reception, the most critical design element is the antenna’s ‘gain’. A high gain antenna will receive a stronger signal power and a better quality signal than a low gain antenna. You may also get an antenna with some degree of 4G or 5G filter built-in to assist in reducing noise or interference (see more details below).

For more information, visit our more detailed look into how to choose the right TV antenna in Sydney.

2. The TV Antenna Mount or Mast and Antenna Alignment

The type of antenna mount you use can actually improve the quality of your reception due to one important factor – height. The height of antenna mount can make a HUGE difference to the signal quality and power you receive at your TV and is often the difference between having some reception or no reception. In some areas, where you have line of sight to the nearby signal transmitter, you will only need a short ~1.4m tin or tile roof mount. In other situations, you may need a 15ft guyed masted, or even up to a 50ft guyed mast. Yes, we still install 50ft (~15m) guyed mast on the top of 1 or 2 storey buildings. This can mean up to 70ft above ground level! Thankfully, with digital TV signals, this isn’t required nearly as much as back in the days of analogue TV.

In addition to the type of antenna mount, you will also need to consider the alignment of the antenna (to ensure it is pointing towards your desired transmitter) and placement of the antenna mount on your rooftop. There may be trees or foliage (or other tall buildings) you will want to avoid, whilst trying to get to the highest point on the roof for the most reliable signal.

3. TV Antenna Booster (with 4G Filter)

Whether you have a VHF or UHF antenna, depending on your location, building height, number of TV outlets and type/length of cable runs, you may need a TV antenna booster

Digital TV signal has two main components: (i) signal power; and (ii) signal quality. Whilst signal power can be adjusted with the assistance of a TV antenna booster (also called an antenna amplifier or TV signal booster), you cannot improve signal quality with any similar device. 

Signal quality will be primarily determined at the antenna (type and location of the antenna). If you are experiencing poor signal quality, you will likely need to replace the antenna with a better one or relocate the antenna to a different location (normally higher) in order for it to receive more signal.

Signal power, on the other hand, can be increased with a TV antenna booster, or decreased with an attenuator. Signal power decreased for a number of reasons. You may be in a poor signal area (a long distance from the transmitter), have a large hill between your house and the transmitter, be splitting the signal between a number of TV outlets in your house, be using old high-loss cable, have long cable runs, or something else. There are many factors that contribute to signal loss in a TV system that results in the need to use a antenna booster to amplify the signal.

When using a TV antenna booster, there are 2 main things to lookout for. 

The first is that you do not want to overload the signal (by turning the amplifier up too high). TV tuners can only process signal when it is received within a specific signal power decibel (db) band. The TV tuner will not work with a signal power level that is too low, and will also not work with a signal power level that is too high!

The second warning is that a TV antenna booster does not know which signals are used for TV channels, as compared to AM radio, 4G mobile phone signals, or any other RF signal. As a result, it is important that you are not amplifying unwanted 4G signals that can cause interference with the TV signals which we want to isolate. As a result, many TV antenna boosters these days have in-built 4G / LTE filters.   

4. Lead-in Cable

The lead-in cable connects the antenna to the next device in your TV system, which is normally an antenna splitter located in your roofspace. The lead-in cable should be of the highest quality as it needs to keep signal levels as high as possible, and also needs to be weather (sun and rain) resistant.

As a result, we recommend the use of 50ohm quad shield RG6 or RG11 cable only. Four layers of shielding is the premium standard for TV cabling in Australia and ensures protection from the elements, but also ensures that there is no other unwanted RF signals entering our cable and causing interference.

5. High Isolation RF Splitter

The antenna splitter may look like a standard device, but beware of the small but subtle differences between the types of splitters available. The first important feature is the frequency able to be passed through the splitter. Whilst Free To Air TV reception (VHF and UHF) all sit below 850Mhz, if you need your Foxtel reception to pass through the splitter, you may have to increase the quality of your splitter to pass up to 2400Mhz. In addition, you will want to look out for high isolation splitters, as they will result in one port of the splitter not having any impact on other ports, which can cause issues that are sometimes very difficult to locate.

Splitters come in various sizes, from a simple 2way splitter up to an 8way splitter. They can be ‘daisy-chained’ so as to serve more than 8 TV outlets from the one antenna, however, each time you split the signal, you lose signal power. So, in a system where the signal has been split, there is a greater chance of requiring a TV antenna booster in order to return the signal power back to a level that can be used by your TV tuner.

Finally, splitters can have certain ports that are ‘power pass’. This means that a small electrical current can be passed from the TV outlet up the TV cable to any booster that is normally located near the antenna. Boosters need power to operate, and so without the coaxial cable allowing electricity to pass through, and without a splitter that has ‘power pass’ ports, there is sometimes no way to get it powered up.    

6. Outlet Cabling

Outlet cabling runs from your splitter to the TV outlet or wall plate. Depending on the type of cable used, there are maximum distances that the signal power level will remain in tact before it becomes too low to work. If there is a very long cable run, you will need RG11 cable, otherwise, we recommend the use of a high quality quad-shield RG6 cable.

7. Wall Plates

Wall plates screw onto the wall (much like a power point) and allow you to plug in a short patch or fly lead from the TV to the wall. Wall plates don’t look like much, but comprise of a C-clip, the wall plate itself, a cover plate and a mechanism. They can come in a variety of colours and styles, so you can have a ‘double gang’ or ‘triple gang’ if you want more than one TV point in the one location, or you want to also have a data point on the same wall plate.

8. TV Booster Power Supply

TV boosters require power to operate – ie they are an ‘active’ device. Thankfully, we have a way to get power to them without placing a power point on your rooftop!

The coaxial cable that we install to send the signal from the antenna to your wall plate is actually capable of sending a very low electrical current in the opposite direction! The TV booster power injector and power supply is the device that ‘injects’ power into the cable and sends that power (normally 13V or 18V) up the coaxial cable, all the way up to your TV booster. As you already know, this will only work properly if you have a splitter with a ‘power pass’ port on the right cable!

9. TV Fly Leads

A TV fly lead is the short piece of cable that connects your TV to the TV wall plate. It should not be underestimated in terms of its importance, and we have had many situations in the past where a poor quality fly lead has caused many issues. 

The first thing to look out for are that the fly lead is made of high quality cable. Again, we recommend the use of quad-shield RG6 cable.

Secondly, you will not want the fly lead to be very long, or have many joins in the cable. Given fly leads can sometimes be very low quality (especially those that come with the TV or that you can buy in your local electronics shop), you will want to make this cable as short as possible (no more than a few metres).

10. TV Tuner

The final piece of the puzzle to ensure you get perfect digital TV reception is the TV tuner that sits inside your TV or set-top box. Whilst there are situations where you have a perfect digital TV signal at the end of your TV fly lead, if the TV tuner in your TV is faulty or broken entirely, then you will not receive a reliable video/audio experience. 

Unfortunately, with TV repairers few and far between, this means you can either buy a TV set-top box to perform the TV tuner function on behalf of your TV, or you will have to buy a whole new TV!

So, there you have it – 10 steps to get perfect digital TV reception in Sydney. We hope this helps for anyone trying to get their TV reception back up and running.

Please note that this was intended for a small residential TV system, and in larger apartment complexes, and with Foxtel installations, there are many more factors at play and there may be additional parts and equipment required to get you back watching TV again.

Digital TV Tuning Frequencies In Sydney

Manual Digital TV Tuning Sydney

In order for your digital TV tuner to display picture and audio on your TV, it needs to be tuned in to digital TV signals that get broadcast from a nearby TV transmitter. In Sydney, there are 4 main transmitters that can be used. Those transmitters are located at:

  • Artarmon (VHF; main Sydney transmitter)
  • Kings Cross (UHF)
  • Kurrajong (UHF)
  • Wollongong (UHF)

Digital TV Auto Tuning

Most TVs have an ‘auto-tune’ function which will mean the TV will do all the hard work for you and search for all DTV signals (and also FM radio signals that are being received by your antenna). However, if that is causing you issues (perhaps it is tuning in the wrong channels from the wrong transmitter by mistake), then the manual digital TV tuning option is the one to select.

Digital TV Manual Tuning in Sydney

If you are having issues with your TV’s auto tuning option, and have decided to try manual TV tuning, then here are the frequencies and bands you will need to select.

The first step, however, is to check what type of antenna you have got on your roof. Digital TV antennas in Sydney are designed to be either:

  • VHF only (Very High Frequency). These digital antennas have longer elements (arms).
  • UHF only (Ultra High Frequency). These digital antennas have shorter elements (arms), and often have more elements than VHF antennas.
  • Combination (VHF and UHF). These digital antennas have both short and long elements (arms).

Once you have discovered what type of antenna you have got, you will need to ensure it is pointing to the right transmitter (match it up with the transmitters listed above). 

OK, so you know you have a VHF antenna pointed to a VHF transmitter (or a UHF antenna pointed to a UHF transmitter). Now it is time to start the manual tuning.

Digital TV Manual Tuning Frequencies in Sydney

Manual tuning ensures that your TV tuner is ‘looking at’ the frequency wave bands that are carrying the TV channels that you want to watch.

So, let’s take a look at what those frequencies are for each Free To Air Digital TV Channel at Sydney’s TV transmitters.
