Hi, I'm building an antenna similar to the HyEndFed/LNR commercial offerings, based on the wonderful posts by PD7MAA here and others. I'm wanting to experiment with different inductor designs, as well as wire lengths, so I'm trying to build an EZNEC model. Unfortunately, what I've gotten so far isn't correct based on the feed point impedance EZNEC is calculating. I've tried adjusting wire lengths slightly, to mimic the trimming I had to do with the 'real world' model, but that didn't seem to help. I'm certain I'm doing something incorrectly here (I'm new to EZNEC as well as amateur radio/antenna theory/etc). I'm linking to my model, and would very much appreciate it if someone could look at it and tell me what I'm doing wrong. I've been using the help document that comes with the software, but this one has me stumped. EZNEC endfed 1/2 wave attempt Thank you in advance.
