The one I use looks exactly like the one shown, but mine has a small disk at the end of the adjustable BNC probe. No return back to the shell, and the center conductor of the N thruline has a teflon sleeve to prevent any chance of touching the center conductor with the probe.
It works great for desense measurements, and for touching up a receiver front end through the duplexer. I also use mine to couple my counter to a transmitter. 73 - Jim W5ZIT --- On Sat, 7/12/08, Jeff DePolo <[EMAIL PROTECTED]> wrote: From: Jeff DePolo <[EMAIL PROTECTED]> Subject: RE: [Repeater-Builder] Measuring Desense To: [email protected] Date: Saturday, July 12, 2008, 3:18 PM You can get a very nice, silver-plated, adjustable Microlab/FXR sampler (isotee) here for $15: http://www.ridgeequ ipment.com/ store/attenuator s.html I've bought a lot of stuff from Nick and the guys at Ridge Equipment over the years, both direct, via Ebay, and at Dayton. They have a lot of goodies at very reasonable prices - good guys to deal with. I have about ten of these samplers, or ones like them. They're quite handy for desense measurements, getting a sample of transmitter power to go to a spectrum analyzer, service monitor, receiver, or other test equipment that only tolerates microwatts of signal level, using it as a makeshift variable attenuator (terminate the thru-line and adjust the tap to get the desired attenuation) , etc.. I keep one in the lid/pouch of each service monitor, spectrum analyzer, cable kit, etc. so I'm never caught without one. Get 'em while they're cheap! --- Jeff WN3A The one_,___
