SX-1100 HF/VHF/UHF/SHF SWR Meter

SX-1100 HF/VHF/UHF/SHF SWR Meter

The SX-1100 HF/VHF/UHF/SHF SWR Meter is a precision wideband RF measuring instrument designed to be connected in series between a transmitter and an antenna to measure forward power, reflected power, and SWR (Standing Wave Ratio) in RF systems.

The device contains two separate directional couplers/sensors. The S1 sensor operates in the 1.8–160 MHz range, while the S2 sensor operates in the 430–450 MHz, 800–930 MHz, and 1240–1300 MHz bands.

Thanks to this dual-sensor design, it is possible to measure different radio systems across HF, VHF, and high UHF bands using a single device.
