A very rugged Coaxial Switch construction with a definite contact on switch-over. Low insertion loss and VSWR. Negligible cross talk between channels. The switch has a useful range to 10GHz providing you are prepared to put up with some reflection and insertion loss, but the original spec was 4GHz. General Specification: VSWR: DC-1GHz 1:1.06, 1GHz-4GHz 1:1.3 max. Voltage handling: 500Vrms. Attenuation to unused channel: 75dB.
