Mike,
I have many Rohn 25G, 45 & 55 towers with HAM operators on every one of them. I appreciate the fact that their gear (antennas) are made to take a lightning strike :-) Their DB222 antennas stuck out the top of my towers give me a false sense of security, but any security is better than none. I have also found that the HAM operators are very professional and generally fine folks. The only interference issues I have ever had is when the RB532 was emitting out of band emissions from the ethernet port in the 140Mhz range and did create a lot of trouble for us and them at all my sites owned and rented. Cover your ass and get a release of liability for those guys to climb your tower!!
