Default short antennae


"Ian Jackson" wrote in message In
the UK, would you be wanting to rotate it for TV? Don't forget that
one type of antenna used in the very early days of BBC TV (Channel 1,
vertical, 45MHz) was a 'sloper. This was an off-centre-fed wire dipole,
with the short leg being a quarterwave, and attached as high as possible
(maybe to a chimney or a gutter). The other leg was an odd number of
quarterwaves, and attached much lower down. As a result, the antenna had
one of its major lobes sort-of off the end (say 30 degrees off the wire),
in a more-or-less horizontal direction, and responding well to vertically
polarized signals.

I have not kept up with TV signals for a long time. In the US they started
off as all horizontal. I think that some may have gone to circular, but not
sure. It might be the FM stations I am thinking about. Not sure what they
are using now on the digital signals.

What are they using in other countries ? Horizontal, vertical ?
