Last weekend we replaced our outdoor TV antenna with one optimized for high-band VHF and UHF, a so called HDTV antenna. It's very nice.
Time Warner will not service our property because we have no street frontage. What we do have is a hill (since we are geeks it is Geek Hill). On top of the hill is our house. On top of our house is our new antenna. So it's OTA for us.
It was a hazy day so we could not see Mt Wilson but we set it more or less and used the TiVo to check things out. We seem to be accidentally picking up a station in Oxnard CA possibly 100 miles away. But what is odd is that only on my TiVo Premiere XL all of the channels that are usable show a signal strength of 71%.
I'm guessing my distribution amplifier is pulling up the noise floor, and this is skewing the TiVo calculations. Several HDHomerun tuners on the same amplifier show 100% on most, but not all channels, just as expected.
Our channel count went up to 133 from 106 by the way, I believe they are all ATSC. TV in the LA basin is very much multi-ethnic for obvious reasons.
Previously this Premiere did not show 71% signal level on all channels. It's just a curiosity though, as everything is working splendidly.
Our TiVo HD is on a different antenna.
