I am going to rework my inverted vee supported near the top of the 50' tower with polyethylene insulated ladder line (300 or 450 ohm, from DX Engineering, or similar). How far off the tower leg or fa
I slope mine at a 45 to a 4:1 balum, coax into the shack. I would think at least 1'. 73- W1JCW John _______________________________________________ _______________________________________________ Tow
Instead of bringing the ladderline directly down the side of the tower, 'twist' it as you do, thereby changing the distributed capacitance of the two wires to the tower and 'equalizing' any capacitiv
A foot sounds convenient.. But, one can actually calculate this pretty easily. It's mostly a magnetic field problem, rather than a capacitance problem, but the equations are the same. The field from
I'd probably use about 1 turn per yard/meter as it's good for common mode rejection and the extra turns wouldn't hurt (within reason) I have no technical basis for choosing the number of turns/twists
spacing out a foot, the coupling is pretty low regardless of how many turns.. However, another good reason for twists is that it tends to reduce the wind induced vibrations. That is, you don't want y
or if you want to keep the tower from flying off into the air ??? _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@con
I want to see that feedline that can launch a tower!! You must be thinking of some pretty impressive conductors.. 1" ACSR or something like that. _______________________________________________ _____
