Topband: 160 m inverted L

FWIW mine is cut  by trial and error to 1825 and is approximately 65 feet vertical and 80 feet horizontal. I have moved it around to three different locations over the last 2 years. The dimensions change very little, perhaps 2 feet. The SWR can be tweaked by raising or lowering the FCP a little.   

Good luck
