Please supply a post code (or that of a nearby shop) so contributors can look at your location in relation to the transmitters and terrain which could all be significant in your problems.

That would perhaps be interesting for those potentially affected by the presence of 4G signals, mainly those whose local transmitter uses the channels in the high 50s for some multiplexes. Those whose preferred transmitter uses the lower channels, from 21 upwards, are very rarely affected by the 4G transmissions as the frequencies are too far apart. 4G signals occupy the band from about 800 MHz upwards, channel 21 is about 470 MHz, Channel 59 is at about 775 MHz. Some viewers who are close to a 4G base station may have problems with signal swamping, especially if their local services are in the channel 50+ range.Those potentially affected will have had a filter supplied, free of charge, by at800 around the time the 4G service started in their area. If not, they should talk to at800.
So most people are not affected by the presence of 4G.
The majority of problems people report on these pages would appear to have other causes.

John You are not receiving Freeview channels (needs an aerial but you're far too far away) but probably Freesat services via your dish. To get the most available channels you need a satellite receiver, probably of the Freesat type but others are available. Look at Freesat Channels - Free Satellite TV, HD and Radio Channels to see what programmes are available via freesat. Depending on your precise location, you may find a larger dish an advantage as the signals carrying the UK services are now aimed more closely towards the UK. Judging by comments elsewhere on this site, I would venture to suggest avoiding a Goodmans or Bush branded box.

In your case replacing the TV will not be a solution as the problem may be with your freeview box or aerial system. A CRT TV will be too old to have any built in Freeview or Freesat facility. That is provided by a separate box.
What make of box do you have?

michael, too:
In your comments of Tuesday 23rd, you allude to an assumption of coast to coast broadcasting. There has been analogue transmissions across both the whole of Europe and North America, as well as other continents, for many years - but each country has enjoyed programming aimed at just that country, or state in North America. In the USA, there were and still are many local TV broadcasters aiming to provide for their local community. These have now been superceded by digital transmissions in most cases but still with the aim being to serve local communities. In the USA, such broadcasts are on a fully commercial basis plus a PSB provision that is somewhat 'patchy' in the less urban areas.
In Europe, each country has its own range of services that include PSB and COM provision.
There is no way to prevent a UHF signal from crossing borders between countries or states (in the USA for example) so some areas that are near enough to a neighbouring country/state may be able to view programming aimed at other viewers.
An 'access controlled' service, such as Sky TV, can control to a large extent where the service can be viewed - but there are always those who will take, for example, a UK card with them to France or Germany, etc.
In the main, the differences between North American and European provision is because of the way the services developed. In Europe a lot of the earlier provision was of a public service form with commercial businesses joining in later. In North America is has been very much the other way round with commercial enterprise being the largest provision with public service channels joining much later. In the UK, BBC started regular transmissions for London in 1936 (with a break during WWII) and ITV started in 1954 (differing by region) on a fully commercial basis. The change to digital transmission does not really alter that PSB vs COM pattern.

Expanding slightly on Mike Davison's response, the satellite TV signal is broadcast in the 12.7 GHz KU band and down-converted by the LNB (low noise block), mounted on a dish, to signals in the 950-2050 MHz band that is fed via the cables into the back of the Sky or Freesat box.
Freeview reception is from a ground-based transmitter using an aerial, often of the YAGI pattern (there are other designs) to 'collect' the signals to be fed into the tuner input. The frequency range used to be 470 - 860 MHz but the signals above 800 MHz are now re-allocated for 4G uses.

Sam:
If you have any queries like this, an approach to the neighbours would be the best first step. If they are unhelpful then a call to your local planning authority my be in order.
Generally, you need to determine who owns the fence post. If it is yours, as shown by the marks on the Land Registry mapping, then they should have sought your permission prior to attaching the dish. If it is owned by their landlord then they should have sought their permission prior to fitting the dish.
It is not good practice to mount a dish that low down, the fence post will probably not be as rigid as a normal house brickwork mounting, so they may have reception problems, especially in windy weather. Plus the act of walking in front of the dish can cause disruption of their signals (but there are no known electromagnetic risks involved).

I suggest reading the article at http://gonedigital.net/20…sh/, and then using the links to find out your azimuth and elevation plus the skew angle for you location. The dish must not be aimed at 28.2 degrees East of South - it will look at the wrong satellite! (BA147HQ)

I'm using Firefox 32.03 and it fine for me. I've also tried IE11 and that's fine too. I use Windows 7 Pro Sp1.

Have you tried viewing them? Were there any pictures and sound?
