Two comments on this thread.
First I note that many people say how bad their Status 315 is - with which in the main I would agree. However mine was unusable until I did a bit of checking. My installation has two plugs (on the aerial input to the box and on the cable out, and a wall-mounted socket. One of the cable plugs and the wall socket had whiskers of the braid shorting out the centre (signal) core. Remove/remake the connection and suddenly it all works. Here in Harrogate we are about equidistant from both Emley and Bilsdale both at 28 miles and cannot get a peep from either, but in 2008 we were at Cottenham near Cambridge and about 26 miles from Sandy and the picture was perfect (analogue - it is always perfect or not present (one or the other) on digital.) Horse for course I suppose.
Second, choosing a TV for the van. Before buying a TV think carefully about where the TV will reside and where you will sit (or lie) when watching it. Many of the cheaper TV screens go very dark - even negative - when you view from below the horizontal centre line, and this applies just as much to the 'specialised' caravan TVs as it does to domestic. If you see one in a shop rather than ducking and diving to check the picture (if you can) simply hold the TV and tilt it backwards - its the same thing when you think about it. You will find many - even the brand names - do it, some quite badly. I found a Sharp (LC19D1EBK - now obsolete) was the best and bought it, and some Samsungs were OK as well, but most others were unusable. It may not be such a problem if you are able to fit the TV on a wall bracket which has swivel and tilt, but very few small TVs have tilt on the foot mounting. My Sharp does which cracks the problem but its predecessor (Acoustic Solutions) had to have the back of the foot standing on a book (by Boris Johnson as I remember) to make it anything like watchable.
Finally, even though the first couple of times it can be a bit of a bind to set up, satellite is by far the best route if you want almost 100% certainty of reception. You just have to make sure there are no tall trees towards the SE/SSE from your pitch.
