Hairybadger, I have short runs of good quality cable. I get all the stations I want at the mo, even ch5 (except in cloudy weather). I am just looking to the future, just want to squeeze as much signal out as I can. I have tried every branded quattro LNB and many non branded. Integrated and C120 with various feed horns, before settling on my present setup. I was hoping to find out about the SMW AB LNBs just to see if their high price reflected a better build quality with less noise induced by the LNB. Unlike other units which I have happly gambled 20 - 100 pounds to try, this is a big gamble!
