I am wondering if the concept will also work with other impedance feedline such as 600, 300 or 75 ohm twin-line or even possibly with coax. **** Does the feedline act as part of the antenna? I am sure it will, at least up to the 'no-tuner' if it acts like a G5RV, but do you know if the feedline radiates? That answer would be 'no'. I see that the purpose of the feedline length is to get the maximum current at the center point of the dipole. I see a couple of the frequencies are above 1.5:1, which I am not comfortable going over with solid state rigs. Do you think that could be fine-tuned with the addition of a 1/2 foot section or maybe with that and a 1/4 foot section? Based on the fact that the antenna is being fed maximum current at the center, I would guess that this should work. Buck N4PGW -- 73 for now Buck, N4PGW www.lumpuckeroo.com |
