I'm trying to create a model for a slim-jim type of jpole in NEC, but
I'm having a hard time figuring out how the coordinates should go in.
Can anybody help me with some hints? If I can get where each side
basically goes in X Y & Z and the feed, I can probably get the rest.
Or maybe there's a file online somewhere? I wouldn't mind figuring out
how to do a UHF/VHF log either. Thanks,

Go unto:
http://mmhamsoft.amateur-radio.ca/mmana/index.htm
and download MMABA-GAL modeling software. It's free. Included in the
samples is a 145MHz J-Pole antenna as:
\ANT\VHF\J-ant144.mma

For NEC2 output, see utility at:
http://www.qsl.net/ua3avr/
which is the same engine used for 4NEC2 (by the same author).
