[Milsurplus] [MRCA] AT-803 coaxial stub

[W2HX]

Ray et. al., I looked up the specs of the AT-803 and its 225-400. Not very usable for hams (except monitoring some traffic).  I might suggest this antenna instead.

this will cover 2m and 440 MHz and 100W. They accepted a $200 offer, they might even accept lower, who knows.

ray. the official location for the 803 is on the hood of the jeep well forward to allow the hood to be opened afainst the windshield.  i have seen 803 mounted on a pipe on the right side of the jeep between the passenger opening and the front wheel well. on top of the pipe was a smal plate with maybe 6 thin rod radials  about 12 inches long

I have a AT-803 Coaxial Stub antenna that to me looks like a fat vertical dipole. It appears to be designed for mounting on flat surfaces and covers 225 to 400 MHz Want to install it on my M151A1 and use as a receive antenna on the UHF aviation band with the URC-110
Figure I can throw together a bracket maybe attached to the mount of the 110 being that the back of the mutt is somewhat full of sticks now with the huge whip for the GRC-106, medium antenna for the RT-524 and small antenna for the VHF side of the 110 but the issue is that looking at the antenna it appears to me to be a dipole and figuring if it’s a dipole it won’t need a ground plane or radials but in seeing other beer can antennas think they may have had a ground plane attached.
Anyone have any thoughts about if this would need a ground plane or not?
