I have a steel boat so any radio requires an external aerial. I thought I could easily and cheaply convert the backstay by using a pair of insulators. Unfortunatly I found out that the stayloc fittings that I favoured would cost £200 for a pair. This was more than I was expecting to pay. Does any one know of any cheaper alternatives. I wondered how effective taking an insulated cable and winding it up and around the backstay would be. I am aware that the length should be determined by the frequency being recieved. Assistance is requested gentlemen, and ladies of course. I was thinking of getting one of those world band radios but most do not seem to have a dedicated aerial socket. how would I conect the external aerial to the radio. Last year I actualy bought a NASA SSB reciever, the one that is regularly advertised in PBO. when I read through the installation instructions they were expecting the radio to be installed in a house, and specified the aerial be led down the garden and in through a window. When I phoned the technical help line for info for installing in a boat, I was told They did not have any instructions for fitting in boats, and as I was the first person ever to inquire it should be no trouble. My responce was to return the radio and had a refund.
