AN/SRA-23 need photo    Antenna multicoupler AN /SRA-23 consists of three couplers and associated control and blower units. The couplers cover the frequency range 2 to 27 mc in three frequency bands. Each coupler operates in a different band. These bands are 2 to 6 mc, 5 to 15 mc, and 9 to 27 mc. The coupler group was developed for use with 500-watt transmitters, but, with minor adjustments. it is capable of handling transmitters with 1000-watt outputs.
    One coupler group accommodates only one transmitter. Provisions are made, however, for connecting up to eight of these groups together to form a multicoupler system. This arrangement permits the simultaneous operation of eight transmitters into a single broadband antenna.
