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
https://aafradio.org/NASM/Enola_Avionics_Descriptions_-_Radio_Op.htm (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 of

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!!
