Okay, I have what must be a stupid question. I say that because I have looked for an answer and have been unable to find one, so the answer must be so obvious that I'm not seeing it and everyone else

Rob Seems most people using a UNUN (myself included) are using it to transform the 50 ohm feedline to match a low or high Z (but resonant) antenna such as a ground mounted vertical or inverted L. I u

If you connect 12" of RG213/u to a 20 ohm j0 load, the result is 20 ohms +j.7, which is a negligble change. The practical effect is to lower the frequency of the system a few kHz. Since a 12" length

Okay Thanks Tom and Jerry-- the key apparently is to keep the feed real short in terms of wavelength, on the ant. side of the xformer. This won't be difficult to do on 1.9 mhz. Then the characteristi
