I got hold of 240 Ohm twin lead feeder, the type which has been used for TV installations in the 70’s before coax became common place. I want to use it to fed a wire dipole. This antenna should be tuneable with a Z-match on 80, 40, 30, 20 and 10m.
Does someone have experience in what dipole length/feeder length will work? I know that I must avoid having a voltage maximum at the feed point. Before doing the math I wonder if someone has the optimum length found by trial and error.
PS: I will be activating a nearby summit tomorrow, not decided which one. If I get this antenna done this evening, I will include 80m, else it will be 40 and 30m (as usuall).
