A 1/4 wave of wire is resonant at double the frequency it was when grounded - because that is the frequency at which it is a 1/2 wave long... Example: -> A 33 foot 1/4 wave vertical for 40 meters, if
<< Do not weld on 4130 in the high temper states ie yield strength over 100,000 PSI. The weld arc will locally destroy the high yeild strength you paid for and provide a discontinuity that provides a

Hey Pete.... That's an interesting finding.... I have come to trust my Autec, but your findings are far enough at odds with the accepted value for that type of cable to raise questions... Can you mea
Using ladderline\open wire, etc., on resonant, low impedence antennas such as a yagi/quad/dipole, is an unnecessary complication... You get RF in the shack, you have to adjust the tuner, it is tough
