The Midland SWR Meter is a standing wave ratio radio meter used to improve the antenna performance of Midland SWR radios. This meter measures the standing wave ratio of the transmission line and indicates whether there is a degree of variation between the transmission line and the radio antenna. In other words, it helps determine if there is interference with the radio signal getting to the radio receiver so that any interference issues may be addressed to improve signal strength.
Plug the coaxial cable into the "Radio" port in the back of the SWR meter, then plug the other end of the cable into the "Meter" port in the back of the SWR radio.
Press the "Power" button on the SWR radio to turn it on.
Press the "MAT/OFF" button down to put the SWR meter into "Antenna Matching" mode, then press the "POW/SWR" button.
Press the "REF/FWD" button to switch it to FWD mode; adjust the "Tune" and "Load" knobs fully counterclockwise.
Press the "Freq" button on the SWR radio to select a frequency; turn the "S.CAL" knob on the SWR meter until the display shows the SWR value.
