Hi All,
Both Bob and Warren talked about circular polarisation.
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.
73, Pete G6KUI
