I bought a GE Enhanced TV attic mount HD antenna (60 mile range) from
I have two TVs in the house, a 42" Sony and a 32" Vizio. My plan is to
install the antenna and run a coax cable from it to the junction box
where the cable comes into the attic.
1) Can I use one antenna for TVs?
2) Does it matter which side of the attic I install the antenna? I
think the stations are closer to the opposite side of my ranch house
than the cable junction.
The instructions are mute on these questions.
pay attention to the links to other sections about choosing antennas and
general installation hints.

If your signals are weak and the coax runs are long, you may want an amplifier near the antenna end of the cable.
But put it where you can get at it easily in case it needs service.
I am using one rooftop antenna for effectively four TVs:
two actual televisions and two tuners that feed my Tivo-on-steroids PC
I find that I need an amplifier. But I also need to split the
coax...so I bought a splitter that does double duty as an amplifier.
If the in-attic antenna does not work out, consider a rooftop antenna
installed/aimed/tuned by a professional.
The environment and direction of the TV stations are important.
That antenna is likely to be directional.
May be a problem if your stations aren't in the same direction.
Antennaweb.org is a good place to start.
It's likely that you can find an antenna position that works
for each TV station. Problem I had was finding a single position
that worked for ALL TV stations. I had an outside antenna with a
rotor, but that's no help if you time-shift and record several at once.
Reflections are likely to be more of a problem than signal strength.
With my early ATSC to NTSC tuner/adapters, I found that attenuating
the signal helped. I ended up with several tuners with different
attenuation optimized for different channels.
Inside the attic can be a problem depending on the composition of
your roof, the metal running around inside the attic, metal gutters, etc.
Trial and error is the best plan.
I tried out the attic antenna today. It is supposed to have a range of
60 miles and the broadcast towers are around 25 miles south of me. I
pointed it in that direcection and hooked it up to the attic amplifier
where the cable comes in. I then auto-scanned for channels on both TVs.
A total of 8 digital channels were detected. Only one of them was HD
and that was the ABC affiliate. All the other channels were local
useless ones I would never watch. I went back up there and moved the
direction of the antenna around a few times and rescanned. Not much
changed. According to the antennaweb.org site all the major affiliates
should be easily reachable for me.
I am dubious of the attic antenna although my friend who lives 5-10
miles closer to the towers is pleased with his. I may get an outdoor
type and try that next.
coax to the antenna, threw a rope over a branch, and hoisted the
antenna. I could aim it by a cord tied to one corner. That let me test
with a straight connection and nothing to block a signal.
Your problem could be the amplifier. I'd test the antenna with just a

I live within 8 miles of the network stations' broadcast towers, all of
which are within a 5 degrees arc. I'm in a major metropolitan suburban
area. Even with a professionally installed carefully aimed roof antenna
on an extended mast, I didn't have reliable reception on the majority of
stations that use the UHF band. Reception was better in the winter (no
leaves on the trees to absorb signal?) but still not acceptable
regardless of whether I used an amplifier or not. I suspect that even
though the antenna was directional, multipath interference from busy
fixed wing and helicopter air traffic in nearby airspace was largely to
blame. Despite investment in the antenna, I gave up and got FIOS. Only
the digital signals that were transmitted on the VHF frequencies were
rock stable via over-the-air reception.
If I give them my street address, I get a different list than if I
simply give my zip code. I find it much more accurate than antennaweb.
When antennaweb recommends omnidirectional indoor antennas in some
cases, I'm very skeptical. When they make recommendations in terms of
antenna color coding, I'm very skeptical.
Antennas are often advertized in terms of miles. That's nonsense. The
FCC groups stations by the calculated signal strength at the user's
site; I can even click a button to get the decibels for a station.
That's what the consumer needs to know. It correctly shows that I may
do fine with stations 70 miles away but not with one 11 miles away.
The FCC shows the carrier channel for each station. That's likely to be
different from the DTV channel number. If I miss a channel when I scan,
and the FCC shows I should have a good signal, I can probably get it by
pointing my antenna in that direction and punching in the carrier channel.
By showing the calculated strength of signals from various stations at
your site, he FCC site can help you figure out if there's something
wrong with your setup.

The 4-bay bowtie had a great reputation for UHF analog. IIRC, everybody

When DTV came in, all the manufacturers seemed to make little
modifications to the original design. I wonder if they were refinements
to reject secondary paths a little better.
My problems seem to be weather-related, so I suspect that they occur
when multipath distortion comes inline, from similarly strong
reflections at different atmospheric levels.

There is really no difference between an attic antenna and a roof antenna o
ther than mounting and location. (likewise, there is no difference between
an old school TV antenna and a "HD" antenna whatsoever. Difficulty: since
the changeover to digital, channels no longer directly correspond to frequ
encies, so e.g. "Channel 2" may actually be a UHF frequency in your area.)
For good reception, very little beats a proper outdoor antenna mounted abov

There are VHF high band channels being used. I don't know if any use the

also got the UHF loop which is not adjustable except for rotation.
Do you have hills or large trees between you and the antenna farm(s)?
What do you mean by "All the other channels were local
useless ones" ? You have 7 independent stations not affiliated with any
I'm in the Philly area 25 miles from the main antenna farm and get all the
main OTA stations with just old fashioned rabbit ears on the first floor..
A good idea.
Another idea would be to take that long piece of coax and run it up to
the attic, and bring up a small TV, so he can look at the picture
himself and not go through someone else. (I have a cable jack up there
from when I spent a lot of time in the attic, but a temp cable is just
Definitely. I bought an antenna amp from the sale table at Radio Shack.
It was 8 dollars marked down from 30 or so!! Looked new. With my attic
antenna and the amp, I could get almost all the DC stations now.
(Strangely I don't get channel 20 which iirc is in Baltimore where I
live. But I never watched it much anyhow. )
Something went wrong about 2 months later, and I could only get
Baltimore again. There was no difference if the amp was in the
circuit or if it wasn't. Bought a new amp from Solid Signal. So many
choices, I ended up buying the very same amp under a different name. It
wasn't very expensive (about $35 or 40) and I knew how well it worked
before it broke. I wonder if this one will break too, or if Radio Shack
knew something when the cut the price by 75%.
The first time I put both parts of the amp in the attic close to the
antenna. The second time I read th e instructions and it said to put
the power supply half closer to the TV, or in my case the DVDR. (It
runs the power up through the co-ax, at the same time the TV signal is
going down it.
BTW, if worst comes to worst it's possible to use two antennas,
connected through a splitter (which in this case is a merger or
something!) Both can be directional or one can be dir. and the other
omnidirectional. The amp should go after where the splitter joins
them, unless one antenna has a built in amp.
Are splitters for antenna signals different from other similarly looking
splittlers, because frequencies are different? I never paid
