Heh.  A good Yagi is too clostly to build a lot of, especially if you're 
after a narrow signal width.  I'm land rich, but cash poor. *laughs*

Thanks Don.  That leads me to two more questions.

When do feed line lengths begin cause serious signal loss? 

Are antenna switches A Good Thing(tm) or is there significant signal loss 
in them?

I was thinking aboug using a remote switch as what I would spend on the 
switch would be recovered in not having to run multiple feed lines all the 
way back to the house.

tnx!
