Tonight I watched NBC (channel 41.1, real channel 42) and my signal was fine. I then installed the splitter in place of the F adapter, and the visual quality stayed the same. However NBC is the weakest of all my signals. With NO splitter I saw 28-29db strength (good picture). WITH the splitter, I saw 27-28db (still fine picture). But all my other channels are 32-33db.....so I would guess that if I really did use a 4 way splitter to 4 tv's, I might start losing channel 41.1...if each split costs me 1db of strength.
Or maybe that's all bologna. I dunno...I'm just happy to have lots of clean and clear HD broadcasts for FREE!.
Watched 3 football games today from my own couch. It's been a long time since that's happened.
