Recently, I set about replacing the feedlines on my K3LR-type 80m array. Each feeder in the original design is 87 feet of RG-8X. I ordered and received some heavy-duty "RG-8X type" coax and made up t

to before, Yes, but... There's more to a transmission line than just the velocity factor and characteristic impedance.. namely the loss. However, at 80m, the loss won't be too high with either one, a

Certainly true that the coax VF is part of the tuned network, however... There are two possible issues going on here: While you may adjust by the ratio of the velocity factor to get the inside-the-co

Hi Pete, Ive had experience with cables listed as something or the other "type" cable and have found that quite often physical appearance is the only thing the "type" cable has in common with the ori

Yes, that's exactly why I said "apparent resonance." I have an MFJ259B, and have used it to check the VF. It comes in right at .72. The cable is made for the Wireman, and their other specs appear to

Pete: The open-ended feeder is used to inductively load the unused elements, making them into reflectors. The difference between old coax & new coax results in different amount of inductive loading.

I ended something that should have gone to N4ZR directly: And to prove the point, I sent my reply to the list. Sorry! 73, VR2BrettGraham
