I recently discovered that my RCA VH240R distribution amp was causing noise on most of my channels, resulting in signal loss. I believe this is because the signal is already being amplified by the preamp on the antenna mast. Once I removed the distribution amp, signal strength doubled. The problem is, I still need to split the feed three ways: to my Hopper 3, to my HD Homerun, and to a bedroom TV. Do all passive splitters have a 3.5 dB loss?
