UK Caravanning (uk.rec.caravanning) A forum for the discussion of caravanning undertaken by residents of the United Kingdom, whether in the UK or abroad. It encourages the interchange of views on the merits of models of caravan, makes of tow car, accessories, caravan sites, caravan clubs, and other related topics.

I'm thinking of getting a Freeview box in my van and
I need a new arial as well.
Would those permanent ones that fit on the roof give
a strong enough signal to run a Freeview.
(the ones that look like a flying saucer on the roof)


That would depend upon how good the signal is and how it compares to other
signals from alternative transmitters. They are very much a design
compromise in accepting signals from 360 degrees.

They work well under reasonable conditions, but not much use at all for
fringe area reception where a directional antenna would be needed.
Freeview is presently much weaker than analogue, hence the need for
domestic antenna upgrades in some areas.

I am sure that nearly all of the caravan aerial units use an aerial
amplifier and these amps will be of no use for freeview because the
bandwidth is not set for digital transmissions. The only real way is to
purchase a directional aerial and bypass any amplification system that you
have. Of course this you would have to put up and take down all the time.
Life's a bitch. You pays your money and takes your choice.



You could try the 79 quid satellite jobs from Maplin or Lidel.

On the contrary!. The freeview signals are spaced around the normal UHF
channels, so the aerial amplifiers are perfect for helping boost the signal.

A directional aerial will give some extra gain , and used with the booster,
hopefully a usable picture. The TV transmitters are set to give best
coverage for towns, not for sheep, cows and caravanners out in the country,
so the more rural the site, often the worse the reception.

A dish, though cumbersome is the only guaranteed method for reception.

Not so...

The digital transmissions are mixed in amongst the existing analogue
transmissions, so any amplifier intended for analogue would be fine on
digital too.

The only reason for the sometimes required domestic change of antenna
is that sometimes the digital transmission is out side the pass band of
the antenna and that often the feeder is of poor quality.

Both the antennas and amplifiers on caravans are able to cover the
entire TV spectrum to enable them to be used, plus receive anywhere in
the UK.
