Hi Richard,
How about shooting for 112 Ohms, so he can match it with a 1/4 wave section
of RG11.

Hi Tam,

That would be an opening between 30° and 40° (106 to 122 Ohms) with a
gain around 12dBi (11.8 @10° to 11.9 @20°).

Impedance appears to change smoothly through out the full range; gain
and angle less so (but no more than this spread of 10°).
