Dave, K4SV asked: "Wanted to ask if the normal calculation for a 1/4 vertical applies (234/F(mhz) = Feet of antenna for 160 meters using a Rohn 25G section of tower for the radiator (125 foot)?" ========== 13 sections of Rohn 25G is 126' 6" and will be resonant at 1845 kHz over a good ground radial system per my EZNEC tower models. A 3-foot "stinger" on top of that will bring it down to 1830 kHz. 73, de Earl, K6SE _______________________________________________ Topband mailing list Topband@contesting.com http://lists.contesting.com/mailman/listinfo/topband |
