I was not among those discussing a crank-up, don't have one and am unlikely to ever have one. My tower is fixed and both it and the beam will be rated to take normal winds. I am interested in the va

This is an interesting theory on paper, though it doesn't "feel" right ... I need some help understanding it. It is clear that nothing is lost (conservation of energy), whether it remains RF energy

a coupla years ago W1CW made an awesome looking vertical out of a cage of wires which were around rings of PVC pipe.....he took a length of PVC pipe and cut it on the saw into a ton of short pieces..

So, if I understand this correctly, the 14 gauge, nominally 450 ohm line that I bought is actually something other than 450 ohms; and rather than being less sensitive to environmental conditions (th
