with about 18 turns of coax in it, and is about 15 ft from the antenna on one of the supports. The rf field mine Sigma 5 generates with 500 watts from the TenTec Hercules II necessitated the choke setup for feedline and control lines. There was still RF on the lines without the chokes. I use 5 "shepards crook" pot hangers that work well for the feedline support. They are made of green plastic imbedded fiberglass and are sold in most garden supply stores. They also come as straight poles of various thickness diameters. Now all is right with the world, and the antenna nazis from the neighborhood ugly committee dont see it at all.
