Collins 100 watt & 1000 watt Forward & Reflected
Power Meter

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 wattmeters, phenolic rotary switch with knob to select meter scale and a ceramic rotary switch to select an antenna or dummyload. These parts come attached to a Collins 180T-2 remote control unit for an antenna coupler, better known as an SRA-22. The wattmeter parts are all there and connected together. 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. Order (EQP) SRA-22#1 or (EQP) SRA-22#3 below.
