Robert of Surrey Downs SA asks Why is your antenna bigger than my T shape one?


Robert, TV antennas work by using elements, on the front of the antenna, to receive a particular signal and reflectors on the back of the antenna, to bounce the signal back to the element generating gain. Our antenna is modelled on a UHF phased array design and the reflectors are specially designed and cut to help pull in VHF signals in tight signal areas. It is very hard to design an antenna to receive all the channels from channel 2 ( needing long elements) to channel 69 (needing short elements) so a compromise is needed. A T-shaped antenna is a simple dipole antenna and has very limited gain. It wont work very well in weak signal areas.

Martin of Victor Harbor asks why the ampliier or booster is on the outside under the antenna?


Well Martin, to obtain the max gain out of an antenna system you need a short space between the antenna and amplifer. This amplifies the TV signal at its strongest point and gives you good gain to the TV set to cover any siganl lose in the cable. If the amplifier is near the TV it maybe getting a weaker signal than at the antenna so the amplifier will see more noise than signal so it will not work as effectively.
