[TowerTalk] Inverted L Question

[Joe - WDØM]

If you can, move the bottom of the vertical section in/out from the base 
of the tower (assuming it's on one) to see if that change the SWR - does 
on mine.  You may also want to try changing the horizontal length if you 
have/have access to an antenna analyzer.
