In case I am not the last person on the planet to know about these techniques, let me describe a recent station improvement. My situation was the use of 75 ohm hardline with 50 ohm antennas. With a p

Another technique is to use a half wavelength or integral multiple of half wavelengths of the 75 Ohm coax. A half wavelength transmission line will repeat the impedance at one end to the other. So if

Thanks for the posting. I use a L-match sometimes with a small butterfly air cap and air wound coil. This works but I like your method much better. So thanks, Chet. 73....Walter - K5EST - EM48mu - Mi

One problem with this technique is that as the feedline becomes many half waves long, the bandwidth over which the match is good gets pretty narrow. One of my friends used this technique with about 3

Yes, I can see how that could give some interesting effects on HF, where the desired band coverage is a large percentage of the nominal operating frequency E.g. desiring 700 kHz out of 28 megs But at
