[MRCA] M151A2 Commo #3

[MilComm Guy]

Antennas on the truck are the MX-2799 for VHF, this is the early "shoebox"
matching unit, it uses the same cables as the later unit and auto tunes,
unlike the MX-6707 later round unit it does not have a manual tuning knob,
auto tune only.  The lower mast section on the MX-2799 is unique, it uses
the AT-1096 lower mast, you can tell the difference at a glance as the hex
section goes all the way to the top, the AS-1730 lower section for the
MX-6707 round matching unit is machined round at the top.  The upper mast
sections are the same, so if you see a lower section at a show missing the
numbers you will know how to ID it.

For the R-442 VHF receiver it uses the standard AB-15 antenna base.  For HF
for the PRC-47 we have the AB-652 antenna base mounted on the Marine Corps
base supplied in the mounting kit.  I think I probably have 2 more
installments of the commo install, thank you for the positive comments.
