Topband: Inv L with FCP Tuning

[James Denneny]

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
