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-wire tune

Maxwell used to be a contributor to the ARRL Antenna Book and his book ?Reflections? sold through the ARRL. Now neither is true. As to the reason why, depends on who you want to believe; Maxwell or t

You're right! I couldn't believe it as I remembered 213 as being around 1 db for 100 feet at 1:1. But at a lower frequency it is wuite effecient. At twenty meters it would cost you 20 watts out of yo

Yes and no, Gary. Using good coax certainly helps, but as the feedpoint impedance gets very high (like what you get when operating a 1/2 wave dipole on an even harmonic) then losses skyrocket even wi
