I'm working on collocating a 2-meter remote base with our repeater, and naturally every time the repeater transmits, it makes the remote-base radio totally deaf. I've been playing with quarter-wave stubs with some success (and have lots more ideas/experimenting in mind) but would like to hear from others who are running collocated equipment without the aid of cavities/duplexers.
The local repeater is running 30 watts on 146.85 to a DB-224 at about 125 feet. The link is on 145.11 10 watts to an 8-element beam at about 70 feet. The whole purpose of the remote base is to link to another repeater 30 miles away. And before anybody asks, a link on another band isn't a possibility (primarily because of limitations with antenna systems), so it's 2-meter remote base or nothing. Thanks, Mike WM4B
