We were experiencing poor receive at the site. Replaced the unit and receiver sensitivity is once again hot. Anyone want pics of the insides respond direct and I'll ship you the photos.not much to see. a gas tube and what looks like a surface mount resistor in series with the gas tube. 73, Dave Wa3gin _____ From: Repeater-Builder@yahoogroups.com [mailto:repeater-buil...@yahoogroups.com] On Behalf Of Oz-in-DFW Sent: Tuesday, August 17, 2010 4:37 PM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Polyphaser Question Polyphasers have a shunt protection element. It usually fails and becomes leaky so you get a loss/VSWR indication. It can fail open or short. If it's open, there is nothing to detect.
