This website is for technical assistance and has no connection with the broadcasters, so it has no way of altering what is broadcast nor how it is done nor how changes affect viewers.
Ofcom are the regulator responsible and they don't seem, in my experienced view, to have considered the effect on viewers.
No TV set has ever been automatically adjustable to any changes. The older analogue system was planned a long time ago and was not changed at all, except in a few places when Channel 5 was added for some viewers. Freeview (digital TV) is using a different way of broadcasting and the 'authorities' are making changes to allow for more smartphones to access the internet faster, but it is seriously affecting many TV viewers.
If you feel that these changes are affecting you adversely I recommend you contact Ofcom at Ofcom, Riverside House, 2a Southwark Bridge Road, London, SE1 9HA.

The satellite dish used to get the Sky programmes cannot be used for those from another satellite in a different position in orbit, such as Hotbird, because it is pointed at the Sky satellites. Sky satellites are positioned above the Equator and 28 degrees east of the Greenwich meridian, Hotbird is 13 degrees east and the 'old' Astra satellites are at 19 degrees east. The part on the dish that receives the signals, the LNB, cannot 'see' any signals from the other satellites, so those programmes are not available without a whole new dish, which you say you are not allowed. So you cannot get these programmes without permission from your landlord, sorry.

Floyd:
If you live in your own house you can have both a TV aerial, as needed for Freeview, and a satellite dish as needed for Freesat. You would need a 'set-top box' fitted to get the Freesat programmes and you can still have the Freeview service as well. Just be careful how you connect the equipment together.

This website is NOT run the any broadcaster, but is provided by Briantist to give technical assistance to those having reception difficulties and given by technically knowledgeable people, though anyone can offer help. If your complaint is about the output from the UKTV channels, then you should contact then direct at

I assume you mean an LNB? Any LNB designed for reception of Sky or Freesat will work with your Humax Satellite receiver when mounted on a suitable dish aimed at the satellite carrying the desired services. If you need to buy a dish, perhaps look at Amazon but there are other suppliers. To aim you dish, there is some good advice at The Art of Aiming a Satellite Dish - UK Camp Site Articles

Hi Briantist

Thanks for correcting me, but I was trying to point out that your website is not responsible for the content of any broadcaster, no matter what the medium or delivery method.
So Robert Davies should contact BSkyB at
Contact us
perhaps.

The effect you describe would often be termed 'pixelation' when the image breaks up into small pieces, especially on rapidly changing parts of the picture. When watching a fast moving object, such as a racing car travelling across the screen, it is not uncommon on a digital transmission to get a jerky effect. It is due to the amount of picture information on the digital signal not being sufficient to 'keep up' with the panning image. You never had this effect with analogue transmissions, it only affects digital TV, both terrestrial and satellite, as they try to get more programme channels fitted into a crowded spectrum and so reduce the 'bit rate' broadcast. To get as many programmes in as possible, especially the HD ones, the broadcasters use a technique of only sending the changed information but then update the whole image less frequently. So a still, or largely still, image would not suffer the effect (unless the signal quality drops to a very low level) but an image that moves rapidly across the screen will be 'at risk' of breaking up into individual pixels that can be very noticeable and possibly annoying to some.

As Briantist and others state, 'ghosting' is not possible with digital transmissions, it being an effect caused by multi-path reception that shows up on analogue signals as a displacement of a weaker/fainter image to the right of the intended image - usually termed a ghost image. Such multi-path reception of digital signals shows up as a poorer signal quality measure and possibly reception problems that can be specific to one multiplex.

The problem with unpowered splitters is that they seriously reduce the signal strength, to about 1/3rd for each of the two TV sets and assuming they are both plugged in. (1/3rd for each TV tuner and the other 1/3rd lost in the splitter.) If one TV is unplugged the results can be catastrophic as the 75 Ohm matching no longer occurs.
I would advise using a low gain powered splitter designed for 75 Ohm UHF TV use and good quality cables with well fitted plugs. These splitters generally 'isolate' the outputs from each other and there is no significant loss of signal strength, there may even be some gain so be careful not to have too much gain/signal strength. However, cheap splitters can create conditions for interference and/or poor signal quality on some of the signals but others may be unaffected.

Loft aerials | Installing

My father lives in Verwood in a bungalow and has a hill with trees within 400 yards in the direction for Rowridge (IoW). He has two external aerials on a substantial pole, one horizontal and one vertical. He uses your local TV dealer, Bailey's (see http://www.baileyselectri…uk/) and they are very knowledgeable and experienced with reception problems in the town. (I have no conection with them but they do seem to know the area well.)
Dad's reception is mainly good, though bad weather, rain and wind, can affect signals as the tree move.

Searching for the model shows that information is available at
CPC - Over 100, 000 products from one of the worlds leading distributors of electronic and related products. | CPC
The pictures show the inputs as being standard F-connectors and these should already be fitted to the end of the downlead from the Sky Dish.
