I am sure that this has been asked a hundred times before, but now it's my turn. I need communication in a 50 to 60 mile radius from my base. Terrain is piedmont/upstate area of South Carolina, so mainly flat with some hills and small towns. I think GMRS will do what I need, but I need suggestions on equipment, tower height, etc. Looking at a budget of around $3,000.00 to $4,000.00 with 4 or 5 mobile radios. Thanks for your help.
