Not sure how to answer that, Pete (G6KUI). Our circular polarization is
with dishes. I have not heard of circular beams or crossed yagis to give
circular polarization for many years.
My antennae on VHF/UHF are horizontally polarized yagis and as far as I
know that is standard with amateurs Australia wide.
In the summer DX season I can work most areas in our eastern states plus
ZL, FK, and recently YB0. I have also worked KH6, JA, 9M2, P29 and have
heard the XE1 beacon. Most of this would be on Es or on F1 sometimes with
Es extension.
I also work 144 and 432 into our eastern states wth best contact to north
of Sydney - over 3000 Km. This is all on horizontal polarization. The boys
who operate frequencies higher than 50 megs seem to all be using dishes.
Cheers,
Bob VK6BE.

Is that LEFT HAND circular polarisation or RIGHT HAND circular ?
Using Horizontal or Vertical to receive circular results in a 3dB loss
of signal - not very efficient !
As for using circular polarisation on amateur bands, I've been equipped
on 2 metres for over 20 years but only had one contact where we both had
circular polaristion. I've got two crossed yagis in an "X" formation so
that I can have LHC, RHC, Hor or Vertical just by altering the phasing
between the two yagis which is very easy, just a turn of a knob in the
shack.
