100 trips to attic/basement/bedroom on saturday, trying to optimize OTA reception. The result was:
- No significant improvement to OTA reception. All the 'marginal' channels such Fox 25 remain unviewable day or night.
- Still only one OTA antenna "outlet", a short coax direct from antenna to bedroom TV, no preamp or amp.
- Unable to increase # of OTA outlets by using basement patch-panel. Can't use the attic->basement->patchpanel->rooms cable runs for OTA whatsoever. They work fine for redistributing the cable/comcast signal however.
- Antenna remains pointed 10 degrees above horizontal.
My conclusion was:
- Recent/summertime signal problems are as usual for every summer and are due to trees and multipath.
In previous years I would rely on the QAM version of HD-fox-25 during summer, but that is no longer available of course.
- Another few hours of antenna-pointing might result in some improvement. Not sure if I will attempt it. It's so not fun.
I succeeded in getting channelmaster titan AMP demonstrably working but it did not help my reception significantly, whether I ran the antenna direct from amp to TV, or >150 feet down to patchpanel and back to TV through long coax. It did provide a more solid picture on the only two channels receivable when I use patchpanel-runs. Maybe I need the other titan amp , the one with even more power. Or less power. :|
I succeeded in relocating my cable-modem (and home office) to another room, which actually decreases my home office capability (no OTA/antenna in home office now).
I'm not yet considering renting HD-DTAs from comcast, along with paying them an 'hd technology fee' to watch their retransmitted OTA channels in HD.
