[Antennaware] Radial mats under dipole

[Bob Tellefsen]

Dave
For the cutting of your coax to the exact half-wavelength,
set your analyzer to half that frequency.
Connect one end of the coax to the analyzer, and leave the
far end open.  Now slowly trim bits off the open end
until the analyzer shows a very low resistance and little
or no reactance.  This is now a quarter wave stub at the
analyzer frequency.  It will be a half wave at the original
desired frequency.
Good luck and 73
