I tried feeding a wire straight up the side of the 240 ft tower here with matching at the bottom of the wire and coming back down the tower from the top. It did not work and I could not find any way to resonate it with the coil. It seemed to be below the resonance point even though the total length was only 500 ft. Larry VA3LK
