"Fine", of course, is a relative term.  The stub was undoubtedly designed
for around 2.6 ghz.  Can anybody calculate how much is lost when it is
run at 2.4 ghz?  I am wondering if this is a factor in why I'm having 
such poor reception with my Lance BBQ grill and feed.  At DC it measures
about 1 ohm, so the construction might be similar to yours.

My guess is that it probably isn't enough to notice, but I want to look
at everything.

Thanks,

Greg.
