TM-210

terminal box, coax antenna for SCR-609

Notes

Unfortunately, I do not read French. However, the answer to your question depends somewhat upon what year the radio was installed in the vehicle, and in all cases upon what vehicle the radio is being installed in. For about 1943 and later, you should refer to the TM 11-2700 Series manual for your vehicle.

FWIW, the connectors originally installed on TM-210 and TM-211 are not SO-239's. They are AN 3102-14-3P. The mating cable connector is AN 3106-14-3S. You can substitute MS 3102A-14-3P and MS 3106A-14-3S as the only difference is the finish colour.

Not shown in the copies of the Change to TM 11-615 below is the fact that TM-211 is installed on the side of Antenna Mast Base MP-48-A in place of the lower IN-118. The W-128 going to the top of the mast base is crimped and soldered to the terminal mounted on the ceramic insulator on the right side. The coaxial cable plugs into the AN connector on the right. The only vehicles that I know of that used this configuration were all of the Deuce-and-a-Halfs. There could have been others.

I'm not aware of any official modifications where the AN connector was replaced by an SO-239 but if there were any, they undoubtedly would have been a replacement instead of an addition.
