I've been troubleshooting an OTA issue and I'd like to share my observations to potentially help others out.
I will update this post once I confirm the problem and come up with a resolution.
Here's a quick overview of my layout.
Wineguard-1080 roof mounted antenna
3 way even distribution Monster splitter
Quad-coax cable runs
No amps or boosters
Anyway, my OTA experience has been very positive (all broadcasts are within 40 miles)...
With the exception of a single and my only VHF channel. And I'm only having issues with this VHF channel on a single TV, which happens to be my Panasonic TC-P60ST50 Plasma. I'm seeing very sporadic signal strength, and it not getting above 50%
My other TV, a Samsung LCD doesn't have this problem, in fact the signal is nearly perfect. To rule out the cable run and connections I moved the Samsung to the location of the Plasma and the signal still remained perfect.
My first thoughts were (and still could be) the Panasonic Tuner with VHF stations. I upgraded the firmware to the latest version which didn't make a difference. I couldn't find a separate Panasonic Tuner firmware update though I saw that mentioned before.
So I have a few options and a few other things to try...
1) Connect the Samsung back up, in front of the Plasma which will also be turned on, and determine if the Plasma TV itself is causing interference with the VHF transmission (which are more prone to interference than UHF).
2) Attempt to manually tune the UHF broadcast of this same channel (NBC). The UHF broadcoast is in-line and in-range of the other channels that I'm picking up so I'm not quite sure why it's not getting auto programmed.
3) Add a digital tuner to bypass the panasonic one (have not looked into this at all).
4) Stream this channel
Any thoughts or feedback?
I will figure this out... Sunday Night Football depends on it
