All, I had a quarter-wave 80m wire vertical (thanks to a pulley under the limb of an 80ft tall oak tree) with three elevated radials. Worked great.I bought a length of 3-inch OD B&W inductor stock and got some high-voltagedoor-knob capacitors to make an 80m trap. Put it at the top of the 80m vertical, added three 120ft elevated radials and added a wire that slanted back to the house to resonate it on 160m. it took some extra work, but it was a nice duo-band antenna with my single 3CX800 amp. Carl K9LA What about two seperate antennas with a common feed? Have the 80 as a vertical and the 160 spaced from it a foot or so and then go to a L or T at the top? If 80 is an aluminum tube then U bolt on a plate with an insulator extending out for the standoff. CarlKM1H _________________ Topband Reflector Archives - http://www.contesting.com/_topband |
