nowadays, when you go caravanning or when you want to spend some time boating, you can keep up to date with your favourite tv programmes.
all you need to do is follow these simple guidelines that we will comment for you.
as you travel with your caravan, each time you stop you may encounter a variety of different problems in the reception of the tv signals.
- to position your antenna, have a look round and see in which direction the neighbour’s antennas are pointing – yours should be pointing in the same way. once this is done, you must tune your tv to the channels used by the transmitter that your antenna is pointing to.
- instead of using a set-top antenna that comes with many portable tvs, it is best to use a good quality outdoor antenna, which will allow you to see clearer and better pictures.
a directional antenna like the nova model, when properly used, will work much better than an omni-directional antenna that can pick up reflected signals (or ghosts).
place the antenna high up.
the higher the antenna, the stronger the signal. to do this, you need to use a long, strong pole that is securely attached to the caravan.
also remember to stack the antenna horizontally or vertically depending on the transmitter polarisation shown on the coverage map.
- the use of a “booster” or antenna amplifier can help you get rid of pictures that are noisy, snowy or grainy.
however, if you are seeing lots of ghosts then don’t bother – a booster will only amplify the ghosts as much as the direct signal.
once again the nova model is able to provide you the solution for this situation:
it features a built-in preamplifier that can be turned on & off from the power supply unit, thus allowing boosting the signal whenever necessary.
- the use of a portable receiver might be a good idea.
many colour and black-and-white portable tvs can be run on the mains or on a 12-volt car battery.
some sets even use rechargeable batteries or dry-cell batteries,
however the down side of this is that these batteries run out and so you have a limited viewing time.
the good side is that portables perform far better with weak signals than larger tvs.
- try to make sure your antenna is not pointing directly towards a tree, building, side of a hill etc., as this will impede it from working properly.
try to park and mount the antenna where it has an open area in the direction of the transmitter – at least for the first 100 metres or so.
you must point the antenna in the approximate direction of the transmitter (which, in all likelihood you will not be able to see) and adjust its angle until you see the best picture.
- your antenna should be horizontally stacked (h) when receiving from a main station, but it should generally be vertically stacked (v) when receiving from a relay station.
if you are receiving from a relay station, try to place the antenna high up, with no obstructions and if possible, from where you can see the top of the tower as unfortunately relays are quite a bit less powerful than the main station.
- however, please take into account that you will not be able to get a good reception everywhere.
tv transmitters reach as much as possible of the population, but if you want to go to really isolated areas, you may find that these are not covered.
transmission standards may differ from one country to another, so if you are taking your tv set abroad you will not be able to see the local programmes (except by satellite).
