Can you fix a broken/ jittery picture on my TV?2020-12-11T00:52:05+00:00

If the breakup is caused by an issue with your antenna signal, then we can almost always sort that out. Sometimes it’s as simple as checking the fly-lead (the antenna cable from the TV to the wall point) and/or running a quick channel scan (Getting the TV to scan for the channels again, just like when you first set it up). We recommend checking these two things first, then if the problem persists, give us a call and we will get right on it!

What causes TV interference?2020-12-11T00:52:39+00:00
Interference is caused by the signal from your antenna to your TV being either weak or compromised. Basically, there’s not enough signal, or there are other unwanted elements messing up the signal quality.
Common causes of this include:
A faulty antenna, cable damage, a broken connection or component (splitter, amplifier, wall plate etc), using the wrong antenna for your area, external interference (Mobile phone towers, CB radios, solar panels, electric fences).
Identifying the problem without proper test equipment can be difficult, so we recommend sending a technician to conduct a full test of your antenna system.
How do I troubleshoot a TV that isn’t working?2020-12-11T00:53:29+00:00
Sometimes the issue is with your TV, and not your antenna system. If you’re not sure if your TV is working properly, here are a few simple things to check:
1. Might seem obvious, but make sure the power cable to the TV is plugged in and switched on. Usually, there will be a little power indicator light on the TV to let you know that the power is connected.
2. Try turning the TV off and on, both with the remote and at the wall socket and pay close attention to what happens on the screen. If you see something pop up, such as a message, try to take a photo or note it down, as this will help us to troubleshoot it if you decide to give us a call.
3. Try changing the input in the TV to a different source, such as DTV, HDMI 1, HDMI 2 etc and see what happens. If you have a DVD player hooked up, trying to play a DVD is a great way of making sure the TV is working correctly.
4. If you can access the menu on the TV look for a menu called Tuning, DTV, Free to air, or signal, and see if you can run a new auto scan or channel scan. The TV will then try to search for available TV channels and will often show you the number of channels it has been able to find. If you can take a picture of this in progress and/or a picture of the summary at the end, this will help us troubleshoot your problem.
Is it a problem for my TV to be far from my antenna?2020-12-11T00:53:55+00:00
The further your TV is from the antenna, the weaker the signal will generally be. So if you have good reception on a TV that is closer to the antenna, but issues with one that is down the other end of the house, it’s most likely just a case of not having enough signal power.
The solution to this problem is a signal amplifier, also known as an ‘amp’ or a ‘booster’. You might have even seen them on the shelf at your local electrical retailer, but beware as not all signal amplifiers are the same, and some of them will not solve the issue at all. In order for a signal amplifier to be effective, it has to be mounted as close to the antenna as possible. Normally this means mounting it on the antenna mast itself. If you try to install the amplifier near the TV that isn’t working, it won’t be receiving enough signal to help the situation.
Our techs will test the signal from the antenna to the TV in order to calculate the system’s loss. Accounting for cable length and quantity of points is key, as this will determine the position and type of amplifier required.
Can you install my antenna inside the roof-space?2020-10-07T16:19:34+00:00

To answer simply, no. To pick up proper signal, antennas should be mounted outdoors in the open air where a clear line of sight will make it possible to transmit. Mounting the antenna inside of a roof can block the signal, causing interference.

Can I use a single antenna to connect all of the TVs in my home?2020-10-07T16:21:41+00:00

A correctly designed antenna system can run multiple TV points. Both residentially and commercially, one antenna can power a whole house or building. Our technicians can correctly install a system using proper amplification and points.

Are all antennas the same? What’s the difference?2020-10-07T16:23:55+00:00

Because the country transmits different frequencies in different areas, requirements vary. Generally speaking, metropolitan areas are on the VHF spectrum while other regions are on the UHF spectrum. Different antennas are cut to specific frequencies to eliminate external interference that others might pick up.

Do all antennas need to be Digital Ready?2020-10-07T16:26:05+00:00

Because digital channels/signals require a digital antenna in order to be picked up, older analogue systems will not work. Additionally, they may also pickup interference such as 4G signals. Your technician will choose and calibrate the proper setup for your area.

I’m a landlord. Are antenna related expenses tax deductible?2020-10-07T16:27:05+00:00


I am a tenant living in a block of flats with a shared antenna system. Who is responsible for upgrading/maintaining my antenna?2020-10-07T16:28:34+00:00

The building manager should be contacted for antenna repair services.

I am a tenant in a rental house. Is my landlord responsible for upgrading the TV antenna?2020-10-07T16:29:45+00:00

While most landlords will be happy to assist you, it is best to check your rental agreement first.

I need Free-to-Air TV in my motorhome / boat. What do I do?2020-10-07T16:32:25+00:00

The satellite service VAST covers the majority of the country and is the best option. Permanent installations on the roof of the motorhome or boat will automatically track the satellite or manual portable dishes and set top boxes.

How do I retune my TV?2020-10-07T16:34:24+00:00

Most modern TVs have a simple menu for tuning that will scan and store all the stations it finds. It is also possible to manually tune for each channel as well. Due to the many varieties of TVs in circulation, it is best to conduct an Internet search for your specific brand. If this doesn’t resolve your issue, we can send a technician out to resolve your issue.

Where is the best place to install an antenna?2020-10-07T16:36:18+00:00

There are many factors to consider in antenna installation; a few of them being signal strength and quality, efficient cable length, and aesthetics. This is almost always on the roof of the home in a desirable place.

Is my TV “Digital Ready?”2020-10-13T21:14:05+00:00

Digital TV is currently available in all areas of Australia. For best results, we recommend a TV that has High Definition Television (HDTV) or alternatively, you can install a digital set top box.

My TV is not receiving any signal… What should I do?2020-10-13T21:16:41+00:00

Although there are many causes for a TV to not receive a signal, this is usually caused by the antenna not having a clear line of sight to the broadcast towers. Anything blocking the antennas line of sight will disrupt transmission. This includes buildings, hills and other geographic features, etc. Elevating the antenna higher will often provide the solution to this problem. The goal is to get the clearest view to the broadcast tower as possible. If you’re having trouble, give us a call.

I think I have a faulty digital tuner…2020-10-13T21:18:03+00:00

Digital tuners can be faulty. Since the ATSC tuner is separate from HDMI and other inputs, the tuner would not affect any other portion of the TV. Try installing the antenna and cable to a secondary TV. If the problem persists, give us a call.

I’m receiving all channels except one! Why?2020-10-13T21:22:04+00:00

It is possible that the channel is being broadcasted at a reduced power. Repeater or translator stations usually have low power outputs, as do TV stations with Class A LPTV entitled to greater interference protection. Some stations run lower power for economic reasons.

The majority of TV stations transmit on UHF frequency. However, some broadcast using VHF. While some antennas pick up VHF signals, it is necessary to use an antenna optimized for UHF or UHF/VHF frequencies.

Changing the location or elevating the antenna could also resolve the problem. If you’re having trouble, give us a call.
