I'm no expert on anything, but I'm under the impression that the
radio equipment I've seen installed in naval combatants has some
pretty hefty shock mounts to improve survival through torpedo and
enemy naval cannon hits on a ship, not to mention firing of the
ship's own large weapons. I seem to recall that even the 5" guns
hit you like a plank on board. The ringing pulse of a hit
throughout the steel structure is apparently pretty big, and those
ATC and ART-13 transmitters have some fairly sensitive inner parts.
There are some folks on MRCA who can interject some better facts
than my meager impressions.

Mike is, of course correct. The TCZ nomenclature
is strictly Navy. I can only imagine that they may have been
shipboard, or maybe shore stations at NAS facilities. Yet, the
only place I've seen them were at 3 different MARS stations.
All gleaned from DOD R&M and such, I assume. I tried to use
a TCZ mount kit on a shoeless ART-13 but guess I was missing
something.... Ted, W3PWW had all the poop on the TCZ... but....

In addition to Jeep's description, I don't know of anywhere
in the Signal Corps inventory that the TCZ was used. It had
that salt water Navy aroma, don'cha know. (running and
ducking...)
In order for it to be used in an aircraft or ground vehicle it
would have needed another pair of support plates underneath with
appropriate rubber shock absorbers. You can see the two ART-13
transmitters in the Enola Gay (one connected to the "liaison"
antenna, the other to the "command" antenna) at

(showing that both have the
standard MT-284/ART-13 shock mount
with rubber pads separating the three levels of the mount.) A
better closeup of the MT-284 mount construction is at the top

The TCZ was simply a ground mounted T-47. It
sat on a 44" (nom) cabinet with an a.c. power supply. The
mount was designed to support the transmitter in a fixed
environment. I saw several in USAF MARS stations...back
when....

Hi Jeep, educate me. What was a TCZ mount for? We know
the army used it in the Enola Gay. Did they use it in
vehicles installations?
Thanks, 73 Wild Bill, K0IKP
Looks like
the TCZ mount vice the aircraft shockmount version.
Very nice unit!!
