     Thanks for the reply Scott,  I'm going to build a 4 bay system
this weekend to test it out.  I found lots of coax in the basement so
I can play around with this impedence feedline problem.  Since I only
use one dipole tuned to 140 Mhz anything would be better.  Even if I
get it wrong I should be able to sqweeze a couple Db out of it!
