I just upgraded to a whole house DSS system (4 rooms, one with a dual tuner TiVo). I am seeing something a little strange. On my three Sony B55 tuners, I see a signal strength of 91. On my Phillips DSR-6000 TiVo, I see a signal strength of 83 on both feeds. The TiVo has the shortest lines from the dish, and I terminated all of the cables myself, so I assume that everything is "OK", or at least consistent in the connections. Also, I replaced a really old single LNB RCA dish and box with this new setup. The old dish/box gave me pretty consistent readings in the 92-93 range. The new dish is an 18 round, dual LNB RCA dish, and I am using Direct TV service. The dish feeds a 3x8 amplified multi-switch. I'm guessing that the differences I'm seeing are simply due to meters that are calibrated differently between the boxes. One more question, I see posts from people indicating that they have signal strengths above 100. How does one obtain a signal strength that high? I live in Massachusetts, and have a very clear line of sight to the dish (well over trees, etc). Thanks for the help!
