Mark: Check your IPB, but some of the TBM's use the AN\104-AX VHF mast, as it was also the forward support for the fixed long wire antenna. Check Fig 178 of Vol 3 of the TBM-3 IPB. Depending on what version a/c you have, there might be some differences in installations.

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 ?
