[MRCA] [ArmyRadios] AB-1335/G Antenna Base(s)?

[W2HX]

Ok thanks everyone. Looks like the consensus is – if there is indeed a capacitor in that protrusion, it is to block continuity from an accidental touch to a power line.  And if there isn’t one in there, then maybe just to extend it deep enough to work through the armor on an M113.

Thanks everyone!

Chk their DC continuity, I believe the long one has a great big door knob capacitor encapsulated in its base.  I have one just like it that’s broken on it bottom end, and the caps right there.

I believe the second base just had move insulation to protect personal in close proximity from the high voltage rf
Power rating should be the same

Hello friends,

I have seen these AT-1011 bases in two different configurations. Attached are pictures of the two kinds I’ve seen. They both appear to have the same AB-1335/G designation. One has a flat bottom, and the other has a bottom that protrudes below the mounting surface. Does anyone know the reason why these two exist and if there is anything electrically different about them? Power handling? Anything?
