Any chance the MAP antenna was of the style from the AD-4 (modified with a pedestal for the VNAF) and the MAP airplanes got the early model radios & antennas?
I've pretty much come to the conclusion that the VNAF/MAP antenna is the older USN antenna, which someone told me is called AT145. Until I learn different, that's what I'm going on. Makes perfect sense--the USN prolly had a warehouse full of the things.
As to what radios they were hooked to--well, I've got pics of USAF flying that antenna on the "borrowed" A-1E/Gs, and of course we've got pics of VNAF (much later on) operating ex-USAF A-1s still carrying their USAF-spec Collins antenna. So EITHER both USAF and VNAF A-1s had the same radios, which were served equally well by both kinds of antenna, OR if they had two kinds of radios and swapped them, both radios worked with both kinds of antenna. Maybe Hook can shed some light on that.
Now as to the
smaller mast or "spike" antenna, right behind the canopy, as seen on almost all USN A-1H/Js, all USAF H/Js I've noticed, and the vast majority of VNAF H/Js: This served the AN/ARC-27 radio. Where is that antenna on Es/Gs? It's built into the tip of the fin--you can see the "radome tan" panel on most pics of USAF gray A-1Es. Most VNAF H/Js had both the short and tall "spikes," but so far I've seen three or four of them that had only the taller spike, located behind the canopy where the short one normally is, and no short one. I have no idea what's going on with that arrangement.
