the no-tuner, all-hf-band, horizontal, center-fed antenna is our old friend, the 80 meter halfwave dipole dressed up a bit. by varying the length of the 450 ohm ladder-line feeding the antenna, we can achieve an swr of less than 2:1 on all frequencies on all hf bands with the exception of the lowest part of 80m. on 75m, we are feeding the antenna with a half-wavelength of ladder-line. on 40m, we are feeding it with 3/4 wavelength of ladder-line.
no antenna pruning required. my transmission line really does tune my antenna system.
