[Milsurplus] AT-803 coaxial stub

[Ray Fantini]

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?
