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... 73,Julio VE3FH

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.
