I have a roof mounted Larsen NMO27. Unfortunately I live in the city and would have to drive for hours to get far enough out into the open to do a proper SWR test.
I lost the cutting chart that came with the antenna. I know I could find it online, but I want to add a 2 1/4” long mini spring off of a NMo800 Ham antenna so I need to know how to factor my cut. Do you think the cut chart will be reliable if I add this spring and compensate by cutting 2 1/4” additional off the whip? Also in that cut chart do they compensate for the little metal piece with the set screws in it, or do I need to minus that plus the spring out of the cut? Thanks. Radio is working OK but I’m staying off it until I get this cut down right. Will be out in the country sometime in January so I can test SWR when I’m down there.
