Jim,
Did you build the isolation transformer exactly as described in K2AV's 
article?? By exactly I mean using "teflon sleeved double polyimide insulated" 
wire. I'm not planning on using it with more than 100W...

Gary, I use an inv L with K2AV FCP and matching balun.  I purchased a RigExpert 
AA-30 to tune out the reactance.  It worked great.  No tuning cap or inductor 
were needed.  It took just a couple cuts to dial it in.  My L is now 126 ft 
long with a 65 ft vertical leg standing a few feet off a tree trunk. The SWR is 
now much sharper as it should be.

We live on a small lakefront lot and there was not sufficient room for a decent 
TB ground radial system.  Our location is semi-rural.  So, man-made noise is 
not a frequent issue. The FCP and trimming of the antenna has produced a major 
improvement in the L’s performance.  It enabled me to reach TB DXCC  this past 
season.

Best Luck
