Expert Digital TV Antenna Installation

In 2012, analogue frequencies that have served us for 54 years since TVW channel 7 commenced transmissions on the 13 October 1958, were turned off for good. If you are getting pixellation (squares onscreen interfering with the viewing) dont accept that as part and parcel of the digital experience. Call us – we can look at your system and give you an obligation free quote to fix your system.

So what is digital, and should I change my antenna?
Your old antenna is often still capable of receiving digital signals, and If you have no issue with your digital reception you don’t need to replace your antenna. Analogue channels 2,7,9,10 and 28 though still named the same are actually now 40,41,42,44 and 45 in the Digital format.

How is digital different?
Each element on an antenna is measured to half the length of a frequencies wave length. New digital antenna elements are cut/tuned to receive higher frequencies – hence the shape difference with a digital antenna from analogue. If your antenna signal is breaking up a new digital antenna and quad shielded coax cable will help.

So the higher the frequency of a channel the smaller the element length on an antenna. This is why digital antennas look smaller than old analogue antennas. Phased Array antennas are another tool that help us achieve a better signal – areas that do not have direct line of sight with the transmitter will find their reception improves markedly with the use of the Phased Array type of unit.

Cable shielding. It’s important
Quad-shield coaxial cable is extremely important for your signal reception. If you have old air core or poor quality coax, your digital signals can pixelate due to a high bit error rate. Sometimes your signals can be corrupted by electrical spikes and sparks called impulse interference. Thankfully a Quad-shield coax cable can greatly improve the quality of your signal and shield the digital signal from impulse interference.

Masthead Amplifiers
Masthead amplifiers are used in areas where the signal is too low for a good quality picture or there are so many tv points that the signal hasnt enough power for all – the amp boosts the signal and it can be adjusted from there till perfect.

Fittings and Connections
F-type compression connectors and F-type wall plates are the final piece of the structure that help minimise signal loss and interference – if all these pieces are in place and installed correctly – you will maximise your TV’s ability to get perfect reception.

We’re accredited in My Switch – a government program
We are endorsed by the federal government My Switch accreditation program, which means we meet the criteria of passing the My Switch exam, owning an serial numbered approved digital meter and having $10,000,000 public liability insurance.

if your installer does not have a digital signal meter they cannot fault find – cannot check if the signal is under or overboosted, cannot analyse M.E.R or B.E.R to diagnose issues and rectify them.

if they do not have a digital signal meter all they can do is install the antenna and hope that all the settings are correct as they have no way of adjusting the main parameters which lead to perfect picture. The most common throwaway line the fly by night installer uses is “oh thats just digital” or “thats just Dongara” etc …………………….. its not! – its them!

Please – before you allow an antenna technician to start work on your house ask them if they have a digital signal meter and require them upon completion of the job to supply the signal strength, M.E.R and B.E.R for each channel.
