Just a quick question, some of you may save me some time -
Was looking for polarisation & pattern info on a local FM station in
this pdf:
www.acma.gov.au/webwr/_assets/main/lib100059/radio_2-oct2011.pdf
For polarisation, 'V' and 'H' is clear to me - but what is 'M' both
V&H perhaps?
Patterns are all 'OD', again I'm not 100% certain but presumably this
is omnidirectional?
Thanks for any clarification.

** M = mixed polarisation.
Used to be called " circular polarisation " but that is a bit of a
misnomer.

** OD = omnidirectional, usually only in a narrow horizontal plane.
It is assumed that all listeners are terrestrial.

Thanks very much for the clarification Phil, most appreciated.
