Frequently Asked Questions

What Is Signal Polarity? Do I Need To Orientate My Antenna To Match The Transmitter?

The polarity of the signal refers to the design of the transmitter. Each transmitter mounted on a hill or a building has as one of its design features a method of transmitting signal. The planners decide what the polarity will be. Vertical (antenna mounted on its side) or Horizontal (antenna mounted on the mast in the same plane as the ground.

To experience best caravan antenna you must mount it to match the signal pattern being sent by the transmitter. Failure to do this will result in a major loss of signal.

So If I Have An Antenna Mounted On My Van Which Cannot Change Polarity, What Can I Do?

Not a lot! You could stick to major centres where the signal being sent from the transmitter is powerful. So powerful it will often overcome the problem that your antenna is not mounted for good reliable results. The other thing you can do is carry a second antenna which mounts on the side of the caravan or draw bar. When these locations become a problem get your explorer caravan antenna out. The vertically transmitted signals are often associated with low output transmitters where it is imperative that the antenna is matched for the best results.

How often do I need to change my cables?

Old cables can be very deceptive as they may appear to be fine and yet drop the signal strength level very significantly – even up to half your signal is some circumstances. . If you have any doubt as to the condition of your cables then we highly recommend changing them. They are not expensive and can save lots of time and upset..
