[Antennas] lindenblad antenna

[normn3ykf at stny.rr.com]

Terry,
Saw the bucket lindy link and followed it a while back. I don't have an antenna analyzer for 70cm so trying to build an antenna without detailed instructions is quite a pain. Personally, if I had my dithers, I'd love to build it. It would look geek-kool!!

Did see the parasitic lindenblad article. It uses 96 ohm coax as a matching line. No idea where to get that. The amsat one uses 300 ohm feeder for the matching sections. Easy enough to find that.

Oh, and the standard version http://www.amsat.org/amsat/articles/w6shp/lindy.html table 1 (all the way at the bottom)talks about spacing. Any idea as to exactly what he's referring to?

Thanks for the reply.
