It?s a common situation on boats, especially cruisers that TV reception on the water can be a problem. Most land- based TV aerials are very directional, and they are pointed to the TV station. This won?t work if you are on the water and can be anywhere. You cannot therefore use a directional antenna which can have quite high passive gain. You must use an ?omni- directional? antenna which has no natural gain, and then amplify it. To make matters worse, most existing systems on boats are useless because - as you know - all the TV channels have changed. The boat TV systems are listening for signals that no longer exist. If any of these problems relate to you, perhaps you should look at the new Pacific Aerials ?Omni Pro? marine TV antenna system. If you spend a lot of time up in the remote reaches of the Hawkesbury, even we may not be able to help you. But at least with this system you may still be able to see some cricket this summer! Comes complete with weatherproof omni antenna, mounting hardware, wiring & converter box.
