[QUOTE="FRINGE, post: 882185, member: 336363"] Well, the wife came back with two more more LNB's for me to try; a new Invacom quad to replace my existing one (was bought October 2009) and an Inverto Black Pro quad ( to see if it is better than the Invacom). I tried the Black Pro 1st. Weather was excellent, no cloud or wind. Results were not impressive. Using the % readings from my Tecnomate TM-F3/5 they were down by approx 5% - so got nothing worth watching, just pixelated or 'no signal' screens. Next came the new Invacom. Well, that put the theory of deterioration over time to bed. The new LNB was under performing the old one by 2%. So I'm back where I started with the old Invacom Quad and the TM-F3/5 combination giving the best results. Now I am aware that you can have a box full of (same) LNB's and each may perform better than some others but, unless I am prepared to buy a dozen or so Invacom's (which I am not) to test the theory, I will never know. Maybe my original LNB was an excellent performer from the outset, but has now deteriorated to perform very well (compared to the new one). Then again, it could be performing as well today as it did in 2009. Nobody knows. I am still doing some daily signal strength recording and will post results next week - just for interest. [/QUOTE]
