Does anyone know how you use shielded cat 5 when the radio's are all Tranzeo with their plastic Ethernet port??? Trying to solve a interference problem with some hams myself.

Yep, use shielded ethernet cable and there won't be problems. Even use shielded indoors. Being they are not doing for money, the amatuer crowd is also somewhat apt to ignore OSHA and many of the modern safety concepts like fall protection. Unless you specify your safety requirements, you might see a guy up on your tower in an old bosuns chair with 30 year old rope, or perhaps an old pole climbing belt. I agree they could be a good folks to know and work with; they could be a good inside connection to lots of other towers and businesses. If you have any electrical and RF skills, it's not much work to get an amatuer radio license; read a book, take a couple classes, and take a test. Morse code is optional. At the very least, they'd feel better understood and some camraderie if you got a license.
