Hi Sam, It's all a game of numbers and balance. The most obvious bang for the buck is vertical antenna sepearation. So you simply shoot for the most you can get.
Charts and graphs are realistic (not a division of Tandy Corp) generic guidelines when the actual antennas used are referenced (mentioned). The more practical answer is to install the antennas and measure the actual isolation or coupling (really just depends on how you look at it). Placing the antennas on different sides of the tower or pole, the antenna gain, vertical beamwidth and design all become part of the system picture. Once you know the coupling or isolation value you can run your repeater adjusted for what as-built values you have available. My first six meter repeater had no duplexers... same site with a smokin' 2.5 watts output on split antennas. Fairly easy to work fixed station some 35 miles away... cheers, skipp > "Sam" <[EMAIL PROTECTED]> wrote: > What would be the guidelines to use for antenna seperation on a > 2 meter machine w/o a duplexer.
