I'm sorry if this is a bit redundant and maybe should be asked in another thread but are you saying that every time you split with a passive splitter you drop 50%? I have my OTA split (passive splitter) in the attic 3 ways, to drop to the family room and to two bedrooms. Then in the family room it is split again to the TV and HR10. I still receive a relatively strong signal except on CBS (bedrooms are fine though). Will I be able to split again in the family rm for the HR20?
An installer once told me that if you further split a split signal your quickly degrade your signal (100% - 50/50 - 50/25/25 - 50/25/12.5/12.5 etc.). He said the best way to preserve the best signal is to use a multi-splitter (not a multi-switch - different purpose). So I'm planning to rewire with a 1 to 4 or 5 splitter.
