- Sorry to inject a technical question into the ongoing controversy, but I
- tried to do the above and got a strange result.
-
- I split the cable after the in-line filter that unscrambles the Disney
- channel and ran a length ~25 ft upstairs. There I feed it into a distribution
- amplifier and from that to two TVs (one about 20 ft, the other about 30 ft).
-
- Everything is fine *except* that I don't get any thing on channels above 13. I
- checked the amp and it is supposed to amplify VHF, UHF, and FM. The splitters
- are supposed to split those as well. I tried adding yet another amplifier
- (again, one that amplifies VHF, UHF, and FM) downstairs right after the split,
- but it didn't make a difference.
-
- Anyone have a suggestion or two?
