We acquired a used 40-2CD (40 meter 2 element yagi) and wanted to test
it out after assembly. Assembly went fine after putting on some new
hardware. We tried testing it on a step ladder just to see if it was
in the ballpark. Turns out that the resonant freq is at 6.90 MHZ, and
above 3 to 1 SWR in the ham band. I know it's close to the ground,
but what else can be done before putting it up? Is this normal? Any
other way to test it? Is following the Cushcraft assembly
instructions dimensions usually close to being correct once it's up?
Any help appreciated.
