Re: [Repeater-Builder] Duplexer tuning with Return Loss Bridge

[Dick]

Gary:   The easiest instrument combo I've used to tune a duplexer is an RF sweep generator and a spectrum analyzer.   Use dummy load to terminate the duplexer ports not connected to the sweeper or analyzer.   If you need more help, feel free to email me directly.   73,   Dick W1NMZ   ----- Original Message ----- From: [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Cc: [EMAIL PROTECTED] Sent: 20 December, 2005 21:48 Subject: [Repeater-Builder] Duplexer tuning with Return Loss Bridge   Gentlemen,     Will be starting a new science project setting up Wacom 641 on 2 meters. Have a Rohde & Schwarz monitor receiver with S meter, DB pads, dummy loads etc. Plus an IFR 1500. But I see comments on a unit called a 'return loss bridge' for the IFR. How important is this return loss bridge and what is it's claim to fame? Do I really need one? Also have an old HP 8554B Spectrum Analyzer. Thanks, Gary  K2UQ   YAHOO!
