I have been modelling verticals and dipoles for some time, but am not very knowledgeable on transmission lines. I wondered if anyone could explain how to add a transmission line or had a file that wa

Many antenna programs have a method for placing a simple transmission line in the model. EZNEC, for instance will allow you to define a very short wire (like one inch) place it just about anywhere at

-- Have to agreeably disagree with Guy on this one. EZNEC does NOT like closely spaced lines according to the documentation, and segmentation on a 1" line at 160 meters would just not be reliable. On

For 40 meters and upwards, you can easily model balanced feeders as 2 parallel wires. (e.q. see tltest.nec as example in the 4nec2 package). If you are not interested in additional losses of pattern

hello Ed, Guy and Dave, there seems to be some misunderstanding... as I see it Guy hasn't suggested modeling a feedline but using the (virtual) feedline option in EZNEC, which will serve Dave's purpo

I *was* referring to the transmission line feature in EZNEC, not a literal modeling of the transmission line wires. [Thank you Ulrich, long time no hear] For modeling linear loading, or placing wire
