These sensors are for 0-100 watt operation and are compatible with WN1 and WN2 systems. They have low insertion loss and are built on PTFE stripline with dual differential detectors. True peak and average power with SWR are displayed on your system, and includes a 50 ohm BNC port for monitoring modulation waveforms.
SHF-1 470 MHz - 750 MHz
SHF-2 750 MHz - 950 MHz
SHF-3 950 MHz - 1.3 GHz

These units have >23 db directivity and will display SWR accurately at power levels > 2 watts.
