An antenna (or aerial) is a transducer designed to transmit or receive Electromagnetic waves. In other words, antennas convert electromagnetic Waves into electrical currents and vice versa.
The antenna and its down lead (cable) are taken for granted by almost everyone, but they are just as important as the TV and in fact (electronically speaking) are actually part of it. Many people will happily spend hundreds of pounds on their television but many are unwilling to spend any more than is absolutely necessary on their antenna installation.
This is an important point because the difference in gain between a cheap “Contract” antenna and, say, an Aussie high gain of the same group, can sometimes be quite small, and will not usually transform a really poor picture into a perfect one, but it will make some difference, and that difference particularly with digital signals, could make all the necessary difference. On the other hand, there are big differences in build quality between many of the antennas available on the market so choose wisely. We stock and use Electrocraft, Hills and Matchmaster antennas which seem to do the job well, all Australian made high-quality TV Aerials balanced for digital.
