Got to agree, the higher the aerial can be positioned, the better. Mrs N and I very rarely watch TV, usually the aerial is stowed away and there it stays. However a few years ago we hired this one with a very simple but effective telescopic pole. It simply fitted into a socket on the deck and extended well above the height of the boat. The aerial looks to be the Yagi type which Nigel recommended. I do recall reception was superb, probably the best we have achieved the few times we've used a TV. I don't suppose this arrangement would present any problems as a DIY job. Should be fairly cheap too!
