I'm thinking of getting a Rohn telescoping mast antenna ethier 30 or 40 feet. Anyone use this type? How big is too big? My neighbor doesnt care if I put one up and my town has no issues with it as long as its not an antenna that needs the base in concrete then I need a permit due to land use issues and watershed things. Would 50 feet be too much? I have plenty of space for the guy wires and stakes just dont know how high I want it.
