A CM-7000 DTV STB is the bare minimum tuner sensitivity that I can live with.
I just brought home a Samsung TX-P3071 HDTV w/ATSC tuner and it is a piece of junk compared to the 7000. (7000 got 2,4,11,13,16,19,22,53, TX-P could not get 2,11,53!!!)
I realize that was Samsung's 1st ATSC tuner (I think) but I am concerned that even with all the new DTV boxes, the 7000 and the Zenith 901 were considered to be "the best."
Does it take more signal to lock in a HD signal over a SD digital signal?
How does "the best" DTV STB box compare to "the best" integral tuners or stand alone tuners?
It would be nice to be able to buy a ATSC HDTV and have it work, but I guess that is never going to be an option for me, right?
So that leaves:
- Buying TV's only with highest rated tuners
- Investing in an OTA DVR box with killer tuner
- Improve my antenna/amp system
A bit on my antenna/amp system:
I have the antenna on a hospital IV rack with wheels so I can position it anywhere on my porch to get signal. I have found one position that gets everything on the 7000. I could find no position which would bring in the missing 2,11,53 on the TX-P.
The 4228 is old and dinged and bent and rusted. I know the new ones are not supposed to be as good as the USA ones, but might I get a few more dB from a new antenna? Still a 4228?
I have .3 acres and was planning to survey my property to see if there is a sweet spot somewhere at ground level.
I really don't want to put the antenna up on the chimney w/rotor but I guess it is coming to that. My porch faces Pittsburgh so it does well in that direction. In the opposite direction (through my house) there are a couple stations that I think I might be able to get. The mast/rotor might solve that.
If there were OTA DVR boxes w/rotor control, I'd be real gung ho to set that up, but I don't think anyone makes any. TVRO had it all over DTV in that regard?
Also, If I have the 7777 mast mount but 150-200' of cable run to TV, I'm concerned about signal loss due to the run. I have tons of RG59 but maybe I should use 6 or 11?
