Hi,
I have the Maplins suitcase one, which I guess must be pretty similar. It's brilliant. Having said that, I took it back after I'd tried it the first time at home, as the Sat I needed (Astra 2)was not in the the preset options and all I could pick up the first time was foreign channels.
Maplins assured me that it would work and to keep trying. So back home I went. This time, on their advice I moved the dish very slightly each time, and I mean millimetres at a time. It was very fiddly - at first. I adjusted the dish and moved it around very slightly until I picked up what I thought was Astra 2 Sat and then used the auto scan to save the channels. As soon as you see BBC1 or any of the ITV channels, you know you're on the right one. As I said, there's a Sat very close to it which is full of German and other foreign channels.
Once you have autoscanned all the channels on the Sat it gets a lot easier. With Astra 2 now as an option within the unit I went through all the channels and added the ones I felt I would watch to the favourites list.
Once you have done this, it's easy. When you set up next time, you simply select any channel from your favourites list and press the "info" button on the controller, that then displays the signal strength abd quality bars for the channel you have selected. You then simply move the dish around very slowly, millimetres at a time, and adjust it for the best strength and quality. I can normally get 100% signal strength and 70% signaly quality. I've used it half a dozen times now and it's been easy to find the Sat and reception has been brilliant.
However the last time I used it, I struggled to get it above 50% signal quality and most of the channels were dropping out. I tried to adjust it as normal but still no joy. I was on a site on a hill facing South, so it should have been OK. I then realised that that tripod on which the dish is mounted was not exactly vertical and therefore the dish and LNB were not exactly vertical. As soon as adjusted the legs slightly to make the tripod vertical, bingo 70% quality and all channels loud and clear. The tripod was only slightly out of vertical, but it made enough difference for the channels to drop out.
So to summarize - persevere; make only very very small adjustments; and make sure it's all Vertical.
I've used it in Bethgelert in North Wales which is surrounded by high mountains/hills and it works perfectly every time.
Hope this helps
