Hi, group. I'm considering an attempt at building a quad antenna for 11
meters.

Seems to be some good info on 11 meter quads he

http://www.signalengineering.com/ult...ment_quad.html

They suggest a 1:1 current balun and even have suggestions for a particular
manufacturer's product.

Cubex is a company I'd contact as they have been in the quad building bidnes
for a long time, they build an 11 meter quad and can probably help you get it
set up right; http://www.cubex.com/cb.htm

Good luck.
