- Ken, et. al, If you are putting up a 160 meter tower or mast, why not just hang vertical wires on the sides for 80 and/or 75 meters with plastic pipe or conduit for a spreader and bring them to the s

- Hi Ken, several years ago I saw interesting approach by S53R, who made 80m vertical split in the middle (at 33' level), with linear loading "coil" (neccessary length of wire in extended "C" shape) at

- Ken, Thats potentially an awful high voltage to be switching with a relay or switch. I think I'd rather use a trap, or even better, use the entire length of the antenna on both 80 and 160, assuming i

- Easier way is feed the tower and use the yankee clipper director system. Either way you will degrade the system by having both 160m and 80 on the same tower performance will be a loss due to this. N9
