Step 1 was to install a long-range antenna in my attic and I successfully picked up all local channels when I connected directly from my antenna to the television.
Step 2 was to see if I could still get reception by connecting my antenna to the cabling system wired throughout my home. This was successful; however, I lost many channels. I'm sure that this is because there are multiple splitters between the attic and my TV.
Step 3 was to see if a preamp would help boost the signal strength. This was successful in getting most of my channels back; however, it completely killed the high speed internet connection which runs through the same coax cabling throughout the house.
So my question for the forum is what I should try to do to fix this problem so that I get the improved signal strength for the TV antenna but so that I also have an active high-speed internet connection.
I realize I could just run a cable directly from my attic to the TV, but I would like to be able to have all rooms with access to the TV if desired in the future. Any suggestions?
