[opendtv] Re: VHF Stations Seek Solutions for Reception Problems, by Doug Lung

One would expect horizontal polarization to be best for long range,
where you're counting on some ionospheric skip, and vertical to be best
for signals reflected from buildings and for those who use whip antennas
with their receivers (e.g. as cars used to do before the antennas became
embedded in windows). Of course, CP should also work best for those with
random receive antenna polarizations, like mobile appliances.
From 1936 on, Lo VHF TV transmissions in the UK were vertically polarized to reduce impulse noise from cars, trollys,etc.
