A question on shunt fed towers. I have a 48' self supporting tower. I shunt feed the tower on 160m and 80m. On 160m, my shunt feed is a single 12g wire that runs the height of the tower about 2 feet from the tower. I've noticed that many people use multiple vertical wires. What's best practice? Is there a difference between using single or multiple vertical wires? Thanks, Kelley - W�RK
