Hilly all around. 1500 foot mountain about 1\2 mile to my west would love to put a repeater up there. MT Beacon Amateur radio club is up there. Getting back to antenna it would be half-duplex I can get it about 30ish feet up a tree next to house or 60 ish feet up a tree In my Field but for that I would need about 200' of direct burial cable. It would be used for a Gmrs and Amateur base station. Still need to find a base radio that will do 2m and 440 at 40-60 watt and that can turn down to 5 watt for Gmrs. Budget for Radio and antenna no more then $ 1,000.00 Thanks Wqww770 Kc2ubq
