[QUOTE="007.4, post: 1052716, member: 175445"] Well I decided to stick with USALS and the diseqc motor. I removed the elevation bracket from the old dish and mounted it on the CM90 back plate. I had to fabricate some extensions using some old angle iron to get it to fit. I kept same angular settings on the motor and used the same elevation on the dish. At first I was puzzled as to why I got zero signal when I first tested with the CM90. Then I realised that the offset angles between the old and new dishes were different. Approx 17° and 23° respectively. The elevation setting was at its limit so I had to fit some packing shims to get the correct elevation. I then got a stonking signal! I knew the CM90 would be better than the old cheap steel 80cm but I was greatly surprised at just how much better it was. I can now pull in 4 or 5 satellites that previously had no signal and many weaker transponders on other birds too. [ATTACH]117867[/ATTACH][ATTACH]117868[/ATTACH] A fantastic result for just £10 and an enjoyable day tinkering :) Tomorrow I'm going to paint the dish with some water soluble green Ronseal One Coat fence stain to blend it into the bushes.
