Phil, I understand your point. But, if I were to mess up again somehow, then I'd not have any more replacement grippers to switch. I suppose I could buy a spare socket. But I'm not sure if or where t

True enough ! sound pressure levels on the db A scale. They ran something like this, although my recollection of the numbers may be slightly off, by a matter of a few dBA. 80 dBA - unlimited time of

One listens not to the two tones, in an effort to discriminate them, but rather to the slow "thrummmm thrummmmm...." that repeats at very low speeds when you get the tones close. That is, the amplitu

I think the point being missed here by one of the posters is that if the feedline is really excellent....like the 1/2 inch Heliax, or perhaps 450 ohm transmitting ladder line, or less radically, perh

Exactly Hey guys: In his book, "Reflections", Maxwell states that all power fed into the transmission line (minus line loss) is absorbed by the load, regardless of the mismatch. Secondly, with open-w

((Some content deleted)) Your point is that the better the feedline, the lower the losses, and open wire feedline is best. All true and I totally agree. The point is, if you use the very best feedlin

Well, I would not call it an antenna tuner. It does not affect the electrical properties of the antenna itself. The antenna's physical properties do not change either. So, if at the operating frequen

Well no, you still will not alter the antenna. Its still the wrong length or whatever it was in the first place. You just transform the impedance out at the antenna, before the feedline, rather than
