Freeview

Freeview is a digital tv service that allows you to watch around 40 TV channels via your TV aerial. You don’t need a satellite dish, and there’s no subscription, no ties, no contracts. Just buy a set-top box for free access to the Freeview lineup…

                                                                              How do I get Freeview?

Here’s what to do if you’re looking to get Freeview’s extra channels:

  • Check Coverage
  • – To receive Freeview, you must be in range of a Freeview transmitter. Then give Chapeltown Aerials a call on 0114 2465198 or 07876363015.

Digital TV – TV aerials and connections (Freeview)

Digital terrestrial TV services such as Freeview come to your TV set via an aerial. Ideally this should be mounted outside and as high as possible. You may also get good reception if it is inside, for example in the loft, but a set-top aerial may not be satisfactory.

To get the best reception you need to make sure that your aerial is in good condition and is pointing towards the best local transmitter. An outdoor aerial can deteriorate or be knocked or blown out of its correct position, and cables and connections from the aerial to the TV set can become corroded. Older aerials, cables and connections may need replacing, especially if you live near the sea where corrosion can happen quickly.

Reception problems

Picture break-up, clicking sounds or no picture at all may mean that the signal reaching your set-top box or digital TV is too weak.

If you have had this problem for a long time, you may need to upgrade or replace your aerial.

If the problem has just started, check  today’s transmitter work to see if your local transmitter is affected, and try  resetting your set top box or digital TV. If possible, check another TV set connected to a different aerial – for instance, at a neighbour’s – to see if that has the same problem.

If only your set is affected:

Make sure that your aerial lead is securely plugged into your set-top box or TV and check any other connections.

  • If there is still no improvement, your aerial may be broken or out of alignment. If you can see your external aerial, look at whether it is pointing in the same direction as others nearby. You should have the aerial and its connections checked for faults.

Unlike analogue TV, you cannot get ghosting with digital TV.

Checking, repairing or installing an aerial

We suggest that work on your aerial is carried out by a professional aerial installer, either one registered with the (CAL) installer. If you are having a new aerial installed in order to receive digital TV, a CAI benchmarked aerial will give the best results.

Communal aerials

If you share a communal aerial (for example, in a block of flats) and you are having reception problems, the aerial may be faulty. See if other residents using the same aerial have the same problem.

If you want to go digital, you may find that the communal aerial is not suitable and needs upgrading.

For queries about a communal aerial, you need to contact whoever is responsible for the building – the management company, council or landlord. There is information about digital switchover for landlords and property managers or just call chapeltown aerials 0114 2465198 or 07876363015.

ANALOGUE TV

With the analogue (existing) television services, the picture quality degrades “gracefully” in proportion to the signal strength. It is possible to have quite watchable pictures with surprisingly low signal strength. Reflections are often only a minor irritation, leading to ghosts on the picture and a variation of picture quality between channels, which many are happy to put up with. Indoor and loft aerials give acceptable performance in some cases.

DIGITAL TV

Digital television is a whole different matter. No longer do we have the luxury of saying “that will do”. If there is insufficient signal level, the result is a picture that breaks up into mosaics and vanishes. The sound is also subject to squeaks and bangs as the levels vary slightly. For this reason, the aerial system needs to be of an approved type and installed to a standard laid down by CAI and the BBC etc. It is vitally important that a digital analyser is used for setting up the aerial and the signal levels balanced to provide a reliable service. In some areas, some channels may not be able to be recieved and in others there may be no digital service whatsoever, despite the apparently good analogue service currently enjoyed.

SIGNAL STRENGTH

The roof covering and end gables of a house can shield the aerial from the incoming TV signals. This can make a big difference to the quality of your picture. A roof which is covered with metal tiles or roof insulation which contains metal can destroy signals completely, making loft aerials pointless. With analogue television signals, a poor signal will cause a grainy or snowy picture. With digital signals it may be impossible to receive anything at all. A poor signal on FM will sound noisy and may drop in and out of stereo.

REFLECTIONS

Lofts will usually contain household items which can reflect the incoming signals, even where there may be adequate signal strength. Water tanks, pipes, cables and all the clutter a household can generate tend to be stored there. Signals are often reflected from those items and the reflections will cause a ghosting picture on analogue TV. With digital TV the reflections may well lead to loss of picture. FM radio will suffer from ‘birdie’ noises etc.

CABLE CONSIDERATIONS

As a rule, the cable pre-installed into houses will be of the lowest possible cost to the builder and so will show high loss combined with poor screening. In strong analogue signal areas this may be less important, but where the signal is borderline or digital TV is required it will not be good enough.
