Advertisements I have a quick question about TV signal splitters. I am using OTA for all my TiVo channels now and when the cable guy installed the wires he put on a 2-way splitter. Each output was labeled as -3.5dB. I needed to add a third TV so I used a 3-way splitter I had laying around. The outputs on that one are 2 of them at 7dB and one at 3.5dB. I am puzzled by these numbers. I understand that it has to do with signal loss but why is one different than the other 2 and how does it affect my signal? I did check one TV and some channels do not seem as clear. Thanks for any help.
