Problems with digital TV reception

We have been experiencing a problem where at two sites in the last week we have experienced intermittent digital TV reception problems in our motorhome - essentially the signal will be fine for 5 or 10 minutes, but will suddenly pixelate and/or drop out altogether for 10-15 seconds, before coming back.

To give some background we have a VisionPlus 540 Ststua aerial with VP5 digital signal booster.  At both sites (one in Brecon, one in St Clears) we had - according to my Android phone app (UK Aerial Alignment) a good strength signal; at the Brecon site the app indicated vertical polarisation, so we rotated the aerial to it's vertical position before aligning as near as we could to the direction shown on the phone.  At both sites we used the booster, as without it we got very few (if any) channels when we tuned the TV (an Avtex with a built-in Freeview tuner) - we got 50+ TV channels at both sites, including the major channels (BBC1/2/3/4, ITV1, C4, C5) in both standard and HD versions.

So, does anyone know why we get this intermittent break up of the signal?  Is it down to aerial direction or could it be a fault with the booster (we notice the indicator light never changes colour).  By the way, I have checked that the aerial cable between the TV and wall socket is a tight fit / good contact.
