As I understand it, neglecting the .95, a dipole with each leg 1/4
wave long (1/2 wave total length) has an input impedance of 50 Ohms. A
dipole with each leg 1/2 wave long (1 wave total length) has an input
impedance of 75 Ohms. I'm using 75 Ohm RG-6 cable to keep costs down,
so I'm probably better off with 1/2 wave legs. At least I'd be half
right that way.
