It's hard to put into text. What I'd like to do, is get back to the more omni pattern if at all possible. The way everything is situated, if I put the antenna on the side of the tower facing through most of our coverage area, I think it will end up with too much gain in that direction, twoard another repeater to the northeast.
Mostly, I'm just looking for a way to model what happens, ideally in something that radio mobile can digest, and I'll work it out from there.
