The HD signals carry approximately 4 times the amount of data per programme as is the case for SD services. That's one reason that the transmission encoding has had to be changed to a more capable system, and hence the need for a DVB-T2 tuner for HD reception. There is a suggestion that a '4k' form of UHD transmission might become available and that requires about 16 times the amount of data compared to SD.

The aerial you need should be a log-periodic design intended for use with a caravan. That design will enable you to receive signals across the whole band used for DTV in the UK and Ireland.
Other designs that are not of the log-periodic pattern will not give such good results everywhere, as is the requirement for a non-static caravan on a touring holiday.
A Google search using 'log-periodic caravan aerial' as the search criteria will show a number of suppliers and aerial options.

If you look at the F's DigitalUK Tradeview box, the blue one just to the right of you name for your latest posting, you will see that Waltham is the least favourable transmitter for you as it is 75 km away and the signal will be weak or very weak compared to that given by the nearby Woodford Halse transmitter, which provides West Midlands services. Oxford is a possibility but that does not give East Midlands services.

Some Freeview PVRs have a setting to control how long the recording continues to run after the supposed end of the desired programme. Check the settings for your particular box, it will tell you in the User Manual/Guide how to that.

Sky recivers do not require the use of the internet at all. You do need a telephone connection however with the revceiver connected to that.
You are not clear in telling us what your problem actually is. Are you having problems receiving the programmes broacast by Sky? Is one of your receivers faulty? (If so, are you paying for Multi-room or for two separate subscriptions?)
To post here you clearly have access to the Internet so you can have a Sky Customer Account and can access that having set up the necessary user information and password. Then Sky can help you directly.

Craig:
They are still being transmitted from Sandy Heath. It could be that your signals are being affected by atmospheric propogation phenomena which is not unusual and affects DTV by inducing the receiver to give a 'No Signal' message when it is in fact having problems decoding the signals it is receiving.
Are your neighbours having the same problem with Freeview? Plus, a post code helps contributors to this site to understand where the difficulties may originate.

The explanation is that the MUxes 1,2 and 3 are transmitted at a higher ERP than the other muxes. So you will receive a stronger signal from the Muxes 1, 2 and 3. If your signal levels for Muxes 4, 5 and 6 are close to the receiver's lower threshhold you are likely to get picture pixelation or break up and potentially signal loss if the received level drops below that threshhold.
Usually, adding a signal amplifier resolves the weak signals but at the expense of the strong signals, as those become too strong!

A few yeaars ago a lot of manufacturers showed 3D TV sets at CES - but they have not been selling as well as had been expected. Spo appearing at CES dpoesn ot make them a 'hit' as it's only a showcase. AQctual sales are the real measure of whether a prioduct is a 'hit' or not.
That many manufacturers may be showing curves screen TV sets only shows that they are prepared to test the concept in the market place.

Not being in that area I have no experience of that service. However, it is usual for such local services to use more directional transmitting aerial patterns as that allows 'targetting' to a selected area and needs less power to give sufficient coverage for the intended audience. That means it is cheaper to operate (less power means less cash needed) and does not interfere so much with other nearby services.

Tricia ITV 3 is transmitted on 690 MHz which is multiplex COM4 (SDN), see Mendip (Somerset, England) Full Freeview transmitter | ukfree.tv - 12 years of independent, free digital TV advice for full detail of the programmes being broadcast as part of that miltiplex. If you are able to watch any of the other services, then your receiver is getting the multiplex. It is worth checking whether you can watch all the other programmes on COM4 using the list shown by the URL given.
