    Great ! Thanks for all these precious informations! I might go for the 35MHz! But FIRST if I just have to make a few adjustments I will continu trying the float! So about your advice: the 3 pin plug is not in the water it is in the dry sub. In the water passes the coax cable fully waterproof. I will dismantle the float (bottle) to add an solid antenna to the central cable! (How should I do this properly?) should I remove insulation from the coax cable? (Should i uncover both the antenna wire and the parasite wire!?) or just the antenna wire? Then can I solder it to a solid metal antenna? ( and finally the length of that antenna: you say the same as the existing receiver antenna: it is itself a coax with 2 lengths: one long length with both antenna and parasite coax, and the end of it is just the antenna without the surrounding coax! Which length should I measure!?). Thanks a lot that is all great info to me! Very best!

      Any kind of metal type or shape for a efficient antenna?
