In the planning stage for my 90 foot insulated Rohn 25 I am at the planning for radial stage. Everyone knows the current price of copper. I plan to have 120 1/4 wave radials. Two questions. Can I use copper clad welding wire - 0.30 Dia.? If yes then how do you calculate the length of wire when sold by the pound? Jim KV4FE On the Suwannee River
