Do I remember correctly that designs such as this are less circularly
polarized at the low elevations than they are overhead? If so, have you
considered the Lindenblad by Tony, AA2TX?

If you're building either antenna specifically for VO-52, you might
consider making it LHCP, which I believe is the polarization of the 2m
signal transmitted by Hamsat. (Tony reports that his RHCP design
nonetheless receives VO-52 well.)

A low noise preamp at the antenna will make a huge difference also at 145 MHz.
