<p style="margin-bottom: 0in; line-height: 100%">Ah! OK, that is
what
I thought you intended: with various tuners the worst viewing was
unwatchable on a weak/distant/incorrectly aimed station. </p>
<p style="margin-bottom: 0in; line-height: 100%">“Everything”
makes a difference: tuner, cable (coax), antenna. With the TV
tuners
seems none list the sensitivity (µV), so pretty much have to guess
and reply on others’ experiences. (One reason why I posted my
follow-up which started this thread.)</p>
<p style="margin-bottom: 0in; line-height: 100%">Use of good-quality
cable (coax): RG-6/U vs. RB-59/U – even then there are multiple
options. Check your cable: I’ve had commercially-manufactured
extension pieces (~18” long) where the center conductor slipped:
was pushed during installation so one end barely touched the
splitter’s connector and the other end extended into the tuner.</p>
<p style="margin-bottom: 0in; line-height: 100%">Antenna aiming:
where the studios are aren’t necessarily where the transmitter
site
is. At my location (house) the studios are in various surrounding
cities west and south but all except one transmitter are at an
Antenna Farm 20 mile south-southeaast.</p>
<p style="margin-bottom: 0in; line-height: 100%">You probably know
all that, just a good review (especially that quirky cable-slid
one!)</p>
<p style="margin-bottom: 0in; line-height: 100%">Most of the
reception problem here seems to be external factors, combined with
tuner specs, I think similar to your issues. Calm wind, good
recordings. Windy conditions, start to get pixelation issues;
seems
to be some correlation with the RF Channel (the actual frequency
the
TV station is transmitting, not its virtual channel), though that
tends to fall apart as locally there are two stations, one RF36
and
the other RF38, both 1000KW, on literally the same tower. yet RF36
will pixelate horribly and RF38 will be a clear picture.</p>
<p style="margin-bottom: 0in; line-height: 100%">As for the Backend
tuners, LIS previously the newer Hauppauge 1609 tuner has worked
well
for me. Admittedly due to a little sloppiness in my quickly
connecting to an antenna the Backend with the 1609 inside is
connected to the antenna and splitter feeding the old Backend with
the 1600 and 2250 tuners. IOW the two Backends are on the same
antenna and so getting the same signal. The new Backend (with
1609)
is recording a 1000% better under mediocre reception conditions
compared to the old Backend.</p>
