[TowerTalk] bandpass filters..

[Jim Lux]

Prompted by the recent discussions of multiple feedlines.

Is there a set of designs for such filters floating around?  (doesn't 
have to be a great one, just something to give someone to analyze for 
a project).  Probably a 10,15, and 20m filter would be sufficient.

I glanced through the ARRL antenna book and didn't find any, and 
before I grind through a synthesis, I thought I'd ask if there's some 
"cookbook" design out there to play with.
