Two additional questions:
1. Some devices, like VCRs have a Coax Out. I think a lot of TVs have these too. If these are unused (but have a coax cable going in), should I put terminators on them?
2. Also, I noticed a grounding block like this in Radio Shack when I was looking for a terminator:http://www.amazon.com/RiteAV-1-way-C...3214046&sr=8-6
Should I put one of these in my coax wiring right before the first splitter in my house to protect against lightning?
There should be a groundblock outside where the cable comes to the house. If not, there definitely needs to be one, unless the first splitter is outside and it's UL listed. Then, it (the splitter) can be used as a groundblock.
Not a bad idea on terminating the VCR out, I guess. Although, the return loss on a VCR's connectors is probably along the lines of 5dB, which means that you probably wouldn't see much, if any, difference.
Some TVs have a second input. Some TVs used to have 3 connectors on the back. One was the main input. There was an internal 2-way splitter, with one side going to the "A" side of an internal A/B switch and the other side going to the second connector on the back, which was intended for a converter box. The output of the converter box would then connect to the third connector on the back of the TV set. The only TV sets that have in and out connectors are CCTV monitors.
