I have a Glyn Guest plan for a freelance sub called "SPOOK". I think it is very old, being a dynamic diver for one thing. It says "Plastic Coated Receiver Aerial Wire" must be insulated from contact with water. This is my first sub model so I'm out of touch with the very latest technology. If this is true, how does one insulate the Aerial? A stiff plastic tube with the upper end sealed? Tape wraps around the aerial?


 One paradox is the operating drawings note DRAG on the fully extended aerial breaking the surface. Well, yeah, of course.


Some enlightenment please!

Hi


I always did seal the end of my R/X aerial if it was out in the water, as I was told that in time water would make its way along the wire by capillary action in to the R/X.

I just used some Milliput to seal the wire also it use to help keep the wire in place Not long after this I started to place them inside.

I think it is always best to seal the aerial wire.

As Fred says, most people operating model subs nowadays seem to leave the aerial inside the dry bit (or the water tight compartment (WTC) so it is perhaps less important. Just stretch the standard aerial wire from the receiver inside the boat. (Referring to 40Mhz here.)
