There was never any separate VHF antenna relay unit as there was with all transmitter equipped versions of the MF/HF sets.  In both versions of the VHF sets, a short coaxial cable ran from the transmitter to the receiver.  And the VHF antenna was connected directly to the transmitter by a second coaxial cable.

>>> Anybody have any idea what the T-23/ARC-5 and R-28 used for an antenna relay?  Antenna feed from the T-23 was coax, and the RE-2/ARC-5 antenna relay didn’t have a post to connect coaxial cable. If an adapter was used, any help identifying the adapter would be appreciated
