I need a suggestion for a solution to a DTV antenna problem,
if there is a solution.
I have a Dish 5000/modulator setup, going into a Panasonic
DST50/PV-HD1000 combo. And I also have an off-air antenna
for reception of local network DTV (and HD, when broadcast)
so that I can record HBOHD from the satellite as well as
local network DTV and HDTV. I also receive the local
Dallas networks via satellite, eliminating my need for
crystal clear reception of local networks off-air. It's
only the local network DTV signals that I really care about
from my off-air antenna.
I live in North Dallas (north of Galleria, just east of the
Tollway). I've installed an outdoor antenna in the attic
of my all-wood 2-story apartment building and had it aimed
quite precisely to the SSW. That's where the map shown at www.antennaweb.org
shows all of the networks to be sending
their VHF and DTV signals from, relative to where I live.
All network VHF stations come in perfectly fine, although
as stated earlier I watch local networks analog VHF via
satellite. Naturally the off-air reception isn't as good
as the satellite-provided feed, for analog VHF.
And most, but not all, of the network DTV stations are
tuned perfectly by the DST50. ABC (9), NBC (41), and
FOX (35) are received correctly so that when I select
4 (FOX), 5 (NBC) or 8(ABC) on the DST50 the partner DTV
channel is automatically tuned and displayed.
However the DTV partner for CBS (19) simply will not
tune. The DST50 shows "input signal found" in green, but
also shows "no channel available", indicating that it is
too weak I believe. Sometimes "input signal not found" is
shown, but if I wait a while it will change to "input signal
found". Nevertheless, "no channel available" is hard.
This is odd, since CBS VHF (11) comes in better than NBC VHF
and FOX VHF, with the latest re-positioning/re-aiming of my
outdoor antenna. In fact, CBS VHF (11) looks great off-air.
You'd think this would bode well for CBS DTV (19).
So what's the story with CBS DTV (19)? Obviously, there's
some problem with reflections or blockage coming from the
south up through downtown or the Galleria area or the new
buildings now constructed on the west side of the Tollway
south of me. Oddly, it seems to affect the DTV channel
more than it affects the VHF channel.
My question is, can I do anything about it? Is there
any alternative antenna which might have better luck with
specifically this one particular UHF frequency? I could
"blend" in the additional special antenna, if it would
Is there a UHF antenna solution that would pick up 19 with
much better quality than what I have now? If so, what is
I'd really like to be able to receive CBS DTV/HD here in
Dallas as they typically broadcast 3 hours during prime time
each night. And they also broadcast basketball, golf, and
tennis(?) in HD, which makes life worth living.
Can anybody suggest a solution? Thanks in advance.
