Hello, I am building a 160 meter vertical antenna, and perhaps incorporate a 80 meter antenna within the same structure. I would like to switch out a top section of the of the antenna by means of a s

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

I have been experimenting for years with my 90 foot vertical with vacuum relays installed across insulators at the 30 and 60 foot level. The reliability problems with the relays are not related to co

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

I believe I have considered nearly every one of the ideas presented below (except the hardwood boiled in paraffin :-) I even started to build some of the solutions, but ran into various roadblocks. W
