Portable telly mountain?

I suppose this is a technical question so I've posted it here.

Now that the timetable for the switching off of the analogue signal has been announced, everyone who wants to continue watching TV will have to buy a new telly or get a box/dish.

But are portable televisions compatible with digital receivers? I get the impression that portable aerials don't get a strong enough signal to work with a box. Can anyone confirm this?

The portable aerial that comes with a portable TV will probably be not up to the job of receiving digital terrestrial signals for a set top box even if there was a means of connecting the aerial to the box (presumably RF out from TV). This does not mean that portable TVs can't receive signals from a set top box that has a suitable aerial. The power of digital transmitter signal is often less than 5% of the analogue signal from the same transmitter. When the analogue signal goes there will be more bandwidth and transmitter power available to the digital channels. In the interim terrestrial viewers struggle by having their channels over multiplexed and pushed to the extremities of the usable frequencies.

Its not your portable TV's you should be worrying about, its your VCR's. Without a suitable twin tuner receiver or VCR adaptor you will be unable to watch one channel while recording another.
