[Jeep Platt]

It certainly appears that way.  So long as there was some sort of stiffener inside the skin.  Learn something every day.....

There were all kinds of variations, Jeep.  Here is another version with cast aluminum clamps on phenolic insulators.  Aircraft manufacturers had quite a bit of latitude in fabricating the mount.

That is the antenna but mine had an open sided box on the bottom for mounting.  Wish I still had it.

OK. at my peril I offer the following. If the antenna in question is a 1/4 wave vertical tapered blade with a "box" base. As I recall it has an N connector.. maybe.  I believe, the painted, copper or brass glove over the wood blade fully covered the blade down to the "box" but insulated.  Again, as I recall there were two strips that provided connection. There is a mounting bolt pattern for attachment through the airframe.  My direct experience, as a neophyte, was in about 1958. I recall paying a few dollars for mine. I also, actually, saw one installed in a sedan outside the same ham store.  The gentleman had cut a hole in the car roof. I saw it...  W3NJT. George Pasquale, owned the store and was a reserve TWA radio op and navigator.

Anybody have experience with the AN/104 aircraft radio antenna used by the USN, USAAF and USAF ? I have one that I’d like to use on the TBM Avenger. The question I have concerns the way the antenna is built. On the example I have, the antenna is mostly made out of wood ( looks like oak ) with some sort of thin metal sheathing ( aluminum?) covering some of the wood. The sheathing appears to be very worn. The questions I hardware these: has anybody seen these antennas when they were new? How much of the antenna mast is covered with metal? If this metal is sheathing, how was it fixed to the mast? Does anybody have clear pictures of an unused AN/104 ?
