As far as I know that unit uses reed relays, and should have no detectable 
loss. I think there might be two models of that, but I have only seen a reed 
relay  version.

The advantage of the one I saw is the low loss and no signal distortion 
using relays. You must run the amplifier relay control through it to be sure 
the protection sequence is correct.
