Tom's excellent message this weekend on use of current mode chokes on a feedline caused me to reflect on(no pun intended) my K3LR-type 80-meter array. It uses four dipoles arranged in a lazy-vee conf
feedpoint, thinking thereby avoid any however, Tom makes feedlines are in the well off to purpose, inductance to do If the feedlines parallel the elements, I'd sure look close at what the baluns do
My problem is that I don't know enough to know how to go about making that judgment -- can you offer any suggestions? Are you suggesting that I might put the chokes at the switchbox end instead, or e
You can probably model it, Pete. Just put in a wire (or series of wire segments) in where the coax shield runs, run NEC, and see how much current shows up on this "coax shield simulation" wire. You c
Actually, the impedance of a bead choke can be found on the mfr's data sheet as a graph of series equivalent R and X vs frequency. Both R and L are functions of frequency. At the risk of sounding lik
Very good advice, Jim. This is a "must have" document if your working with ferrites. 73 de Mike, W4EF _______________________________________________ See: http://www.mscomputer.com for "Self Supporti
Thanks, Mike -- I hadn't thought through the modeling systematically. I see no reason why this shouldn't work. What really motivated me to try to get this right was having 2 of the four dipoles fail
