Caravanning Now - What sort of TV aerial should I
get?
There are 3 types of aerial directional, omnidirectional
and satellite dish.
Pros and Cons of each type:
Directional
Pros:
- Very strong signal that does not (usually) require amplification.
- Unlikely to get on-screen ghosting.
- Will work in poor reception areas.
- Possibly built in radio aerial.
Cons:
- Needs to be 'aimed' at the transmitter.
- Needs to be twisted to provide the correct signal orientation (Vertical
/ Horizontal).
- (Usually) Can not be left attached to the caravan while on the move.
- Doesn't require a decoder box.
- You will only get English language broadcasts in the UK.
Examples of:
- Most probably the aerial you have at home (assuming it's roof / gutter
/ loft mounted)
For orientation instructions see www.wolfbane.com/cgi-bin/tvd.exe.

Omnidirectional
Pros:
- Can be left permanently attached to the caravan.
- Never needs to be aimed.
- Built in Radio aerial.
Cons:
- Poor signal (always needs amplification).
- Requires a good strong signal to produce a good image.
- Suffers from ghosting.
- Will only work satisfactorily in a 'good' reception area.
- Doesn't require a decoder box
- You will only get English language broadcasts in the UK.
Examples of:
- Status which looks like a (small) flying saucer. It might have a radio
aerial mounted from it's centre.
- Omnimax, which looks like an arrangement of wires formed around a
large jam jar.

Digital Satellite Dishes
Pros:
- You can use the same aerial / TV almost anywhere in Europe to pick
up English language broadcasts.
Cons:
- Requires a decoder box and a decryption card to work. ('Free to air'
programs can be picked up with a free decryption card.
- Can take a long time to set up and to aim at the correct geostationary
satellite.
- Taking your home decoder box might break your digital satellite agreement.
Examples of:
The standard Sky dish as (normally) bolted to a wall near you.
If you have a digital setup at home, then it may be possible, after your
1st year with Sky, which requires you to have your decoder attached to
a phone line, to take your decoder with you and to use a second hand dish.
Ground mounts and mounts that are attachable to your van are available,
I'm told.
For instructions on fitting and aligning satellite dishes when caravanning
