Andy - I don't believe this would be an issue. The LED lamps advertised for this purpose typically demand 3W and the current to supply that amount of power from a 12v line would amount to some 0.25A. The radiation from the wire would be less than that supplying your horn, nav. lights, etc. Your antenna is also likely to be at least 1-1.5m higher that the mast. I really wouldn't worry.

Our beloved Family Pilot had a drastic reduction of the stainless steel tube carrying the white light, carried out by the former owner, to reduce the air draft and make her suitable for inland waterways. Now we plan to take to the high seas (well, Blackwater estuary) I wondered about augmenting this with something a tad higher. Nowadays there some extremely efficient LED lamps available that are only anout 45 mm x 20 mm and 10 mm thick - it ocurred to me I could easily cable tie one of these to the aerial mast, which is a tiltable one. Question is, would the thin bit of cable carrying the suply to the LED lamp, running down the mast, affect the propagation of the radio signals? Andy
