Installs between transmitter and antenna for measurement of forward and reflected average (CW) and SSB (P.E.P.) RF power, and SWR. Accuracy is approximately that of the Bird 43; carrier measurements ±5% (typical) of full scale depending on frequency and power. Illuminated meter, sensor switch and LED indicator. Power ratings listed below are for intermittant operation. For continuous mode (CW, FM etc.) maximum ratings vary with frequency and are listed in the instructions. All models have SO-239 connectors except SX-1100 with Type-N. SX600 and SX1100 have dual direction couplers. Requires 12 VDC if you wish to light meter.
