      The RX aerial is about 4″ with 21mm of exposed wire at the end, the boat is balsaply z poxy skin. Supestructure
      lid is plybalsa with brass railings, do I have to put the aerial thru the superstructure lid or just position it in the hull? Could post pics if I knew how! Pics in robin bodger, MTB , album. Any wise words are gratefully received.

          Here are a couple of photos of my Huntresses. You can see that the aerials are taped along the top of one of the bulkheads in one model and underneath the coaming in the other. There's no need to poke them out of the superstructure, and under no circumstances should you try to shorten or lengthen them.

            As long as the business end (the "exposed wire" bit) is above the waterline and not hiding behind metal or carbon fiber or soaking wood, it will work fine. If it is reasonably out of sight, a blob of blue-tack is as good as anything to stop it flopping around.

            Metal definitely deflects the signal, carbon fiber probably does, soaked wood probably absorbs the signal. Old, long aerials were only "sort of" tuned lengths, losing a bit of length by hiding it, nobody noticed. The inch length of the 2G4 sets is very much a tuned length, and shielding it loses all of the signal. But dry wood, resin, plasticard, all are transparent to radio signals. And don't worry about the metal railings, they will not be in the line of sight as far as the radio signal is concerned.
