Hi Terry and all that have been following this thread,

I made a recent post in response to your post on this subject.   Upon 
rereading the post, I agree with Mike that the first part might have 
sounded a little harsh.  I meant it in a joking way and hope you took 
it that way.  I wasnt feeling well at the time and maybe I should 
refrain from posting during these moments.

I never meant that the plane wave antenna had a problem.  In fact, I 
believe this is a creative method of making a difficult 
measurement.  By my very nature, I like to throw stones at a solution 
in an attempt to find potential holes.  The only potential hole I 
thought I found was the termination issue.  At the time I believed 
this wasn't an issue since the frequency the termination started 
dissappearing at seemed too low for the cable length.  I did a spice 
simulation using the transmission line model that gave odd 
results.  The only thing I could think of was some weird phenomenum 
involving a coax with little termination at both ends (I have had 
many real cases of these things happening at work that seemed to defy 
explaination).  Based on my simulation, I was suspicious of the 
transient response and mentioned this to the group hoping that 
someone had tested the antenna for this.  Since my post, I have given 
the termination issue more thought using both an AC and PULSE methods 
of analysis.  I believe I have resolved this in my mind and the 
concern I was first worrying about doesn't seem to hold water.  I 
appologize for seeding doubt in the validity of your antenna 
design.  Keep up the great contributions that you make to the science 
of our hobby.
