Check that Polyphasor with an ohmeter, I'll bet you find a short or resistance from center to shield. Had one go out once, poor RX on a base station was the complaint. Found high VSWR. Polyphasor showed dead short from center to shield. Cracked the housing apart (with a cold chisel) and marveled at the construction. (:-'( It's nothing more than a gas tube across the coax line.

Hi folks, We noticed reduced sensitivity at one of our remote receivers recently. Went out to check things. All looked good. SWR to the receive antenna was good. Check it with and w/o Polyphaser in line. Replaced Polyphaser and tested again. same SWR but sensitivity much improved. Is this typical for a Polyphaser that has reached EOL? 73, Dave Wa3gin
