Hi, I have EZNEC model of a tribander with one feedpoint where 10-15-20m elements are joined with a transmission line of 20mm x 20mm aluminium profiles, the gap between the profiles is 15mm. For the

That sounds like the feed system on my OB16-3. I once looked up the formula for that and it came out roughly 100 ohms. When I used that in the EZNEC model I got almost identical results to the plot

Thanks to everyone who answered and particularly to Rick as this was the calculator I was looking for. It is surprising to see that the transmission line calculator in EZNEC which uses round wires gi
Is there a similar calculator for "angle" conductors - e.g. the "half a square" conductors used in some commercial antennas? Viewed from one end, they might be an 1/2" or 3/4" "L" with the top/bottom
