Collins: Watt Meters - 312B-3,4,5 / 302C1/2

Collins 100 watt & 1000 watt Forward & Reflected
Power Meter

(EQP) SRA-22-KIT
Collins 100 watt and 1000 watt forward and reflected power meter. 2 - 30 MHz. Includes Collins 542-4116-004 directional coupler, 458-0388-00 3" square wattmeter and phenolic rotary switch with knob to select meter scale. These parts come attached to a Collins 180T-2 remote control unit for an antenna coupler, better known as an SRA-22. Some SRA-22 parts are missing or damaged but the wattmeter parts are all there and connected together. You will be amazed at the 'extra' parts you get for 'no cost'. Cut off the end of the SRA-22 for the front panel for your wattmeter. You can also remove the parts without disturbing the wiring and mount them in another cabinet. These parts are what make up a Collins 302C-1 or 302C-2 wattmeter, less the case.
