He was looking to NOT use a duplexer. But yeah, a duplexer AND split antennas is a "belt and suspenders" approach to getting enough isolation. :-) Sometimes sites have this "built-in" when Amateurs are required to join a "site receive" or "site transmit" system to keep the number of antenna spots on the towers used by Amateurs to a minimum. Every site and system is a little different... you just work toward maximum performance by careful planning and running the numbers... and then tweak from there... -- Nate Duehr [email protected] http://facebook.com/denverpilot http://twitter.com/denverpilot
