Ross, In general, physically separate them as much as possible. You do not want the transmitter signal from one sector to overload the receivers of the other sectors. That is a form of self-interference. If you happen to have a copy of my book handy, you can read more about antenna separation on pages 159 - 165. If you don't have the book, then separate 10 feet vertical as a rule of thumb. Other factors such as the amount of frequency separation and receiver selectivity also play a part but that's more engineering detail than I can address here. But now you know why you should physically separate your antennas. Many people in the past have had to move antennas apart to resolve this issue after they initially installed them to close.
