Caravanners: Are You Properly Polarised?
Campers and caravanners may find that they constantly struggle to get a better TV signal and reception when on the road. It's possible that they don't understand the importance of signal polarity. What is Polarity? Transmitters and antennas must be able to efficiently communicate with each other according to the electromagnetic waves. These waves are "polarised" by restricting their electromagnetic field to one direction. Therefore both "sender" and "receiver" must be oriented in the same manner, so the electric field transmitted "
