Most everyone on the planet finds Part 95 for GMRS confusing including the people who wrote the statutes. In any event, as long as you have a GMRS license you can put up a repeater system with a 50 watt max output. The ERP is not covered under FCC reg's, so high gain antennas are allowed. No system ID is required in code but EACH USER must ID with call sign at the beginning and end of their transmission string to comply. You can go to 199.9 feet from ground level to tip of antenna without lighting or alternating paint on the tower, but IF you are within the direct landing or take off pattern of an airport, in some cases you will need to follow FAA marking regulations. [ CFR 95.51 ] You can get to any statute by following the menu here: http://www.ecfr.gov I'll repost that part of the statute here: [ A repeater system is NOT a small base or control station station.]
