I suspect that you still haven't taken the time to study 
k9yc.com/Coax-Stubs.pdf  This question is addressed in considerable 
detail in that Q&A-style tutorial.

I do not believe that a reflector like this should be a substitute for 
studying the basics, simply because this list goes to hundreds (or maybe 
more) people who don't want to be bothered with it. :) That Q&A tutorial 
is "the basics,." and I tried to write it so that it's not difficult to 
understand, even if you're not very techie. I spent a LONG time writing 
it. So please look at that for the answer to this question.
