Apologies for being the newbie in this. I'll admit I am after a quick fix!

Am playing with modelling a 20M single quad loop. Yes I have built one
before with a 75r section and it works fine.

The problem I have is how to represent the 1/4 piece of coax on 4NEC2. A
piece of transmission line seems to have to be connected to a "wire" at
each end and I get an error if I just have one hanging in free space
where the feedpoint is.

I am aware I can do it at the Smith Chart output but I'd prefer to be
able to graph actual Z/SWR.

Thoughts?
