Chris, My thought: Don't bother. You'll need about 72 dB of isolation with a typical GMRS repeater pair, and that calls for at least 39 feet of vertical separation between the antennas. That's hardly the kind of portable antenna setup that is appropriate for search and rescue applications.
Just get an ordinary UHF mobile duplexer with six resonators, and use a single antenna. 73, Eric Lemmon WB6FLY (and GMRS KAF4211) -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of CHRIS ELEYETTE Sent: Sunday, March 05, 2006 5:33 PM To: [email protected] Subject: [Repeater-Builder] portable antenna suggestions hey all, I'm looking for suggestion on a gmrs portable field antenna that can be used for field sar operations. Everyone has their gmrs license and the repeater is approved for gmrs. So I'm thinking of using two antennas instead of a duplexer. Any thoughts? thanks, chris __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo! Mail has the best spam protection around http://mail.yahoo.com Yahoo!
