else!).</pre>

<p style="line-height: 100%; margin-bottom: 0in">I would try
moving the antenna’s location within your attic. Digital TV
reception is quirky: too little signal and nothing, but also
too much will give nothing (is there a signal amplifier in the
feed coax?). More than likely too little signal so try moving
the antenna a few feet from where it is now to see if things
change. If the antenna is hard to move try a temporary one:
the old circular or bow tie antennas are UHF (most digital
stations broadcast on a UHF frequency).</p>
<p style="line-height: 100%; margin-bottom: 0in">Another option
is “something broke” while the roofers were pounding up there.
Possible a connection broke at the antenna. Also possible
inside the housing where not seen – here the test antenna
could be worthwhile.</p>
<p style="line-height: 100%; margin-bottom: 0in">If your antenna
feed is amplified be sure the amplifier has power. Also be
sure the correct coax is going to the input: most coax is
black and so they all look the same!</p>

<p>Yea, been there done all that. </p>

<p>Figured you had but all-too-easy to overlook the basics (BTDT!)
-- AT&T had a training video entitled "It Works Better If You
Plug It In"!<br>

<p>Back in 2020 I wrote a program to run on my laptop that
measures signal strength using a USB dongle tuner (<a
class="moz-txt-link-freetext"
href="http://www.guiplot.com/strength/" moz-do-not-send="true">http://www.guiplot.com/strength/</a>).
I can tune two channels (dual tuner) and watch them as I move
the antennas around (I have two: UHF and VHF with a
combiner/preamp). First thing I did was remove the preamp and
look at them separately. They BOTH went to absolute zero on all
channels in the attic (not just no lock, but ZERO signal!). So
I fed the same cable from the Myth box out through the eve vent
and put one of the antennas on a pole and voila! Worked just
like it had from in the attic before the new roof. I have no
idea what's in that new roofing, but it shields RF really well!<br>

Yes, I use a probably similar tool called femon (dvbtools IIRC).
Can't do much about the roof material and sound like the gables are
90° to the transmitters. Thinking possibly a vent stack mount but
that might not be located correctly either. Just throwing out an
idea.<br>

<p>The placement of the two antennas was critical (which is why I
wrote the app) due to our neighbors' trees. Trying to duplicate
the setup on the roof sounds like more trouble than I am willing
to take, not to mention bolting stuff to the new roof or freshly
painted house. I think my days of antennas are done and I will
be adding to Comcast's $billions (unless our neighbors decide to
take down some trees). :)<br>

<p>Hang from the soffit? ...I'm think I'm out of quirky ideas now!
<br>
</p>
<p>Personally I find Comcast/Xfinity's method of show location (the
'Find' option) underwhelming: almost have to know when the show is
on to find it. MythTV/ScheduleDirect is soooo much easier.
'Course one does have to have a signal to watch!</p>
<p>Good Luck!</p>
