If you were trying to make a half wave stub, couldn't you just do =
this...

11802.8/ (frequency in Megahertz) * (velocity factor of coax) /2.

This would give you an electrical half wave length of coax in inches.

Example:  11802.8 / 14.250 =3D 828.27 * .85 =3D 704.03"
                      ^                ^      =20
                  20 Meters         LMR-400   =20
                                     (85%)
704.03 / 2 =3D 352.02 (Electrical half wave in inches).

Or am I totally off here?
