Barry -

Did you happen to check the resonant
frequency of the traps before & after?

I tried earlier this evening to check them
with my RF-1 antenna analyzer.  I was 
able to get pretty sharp nulls,
but apparently the other elements on 
the saw horses were affecting the 
resonant frequency dramatically.  I'm 
going to try tomorrow with better isolation
from surrounding objects.

P.S. W4IU - tnx for the url for Hy-Gain.
