Remember TV antennas? Well, they still exist. A digital TV antenna
allows you to watch local TV stations for free, all without paying a
dime to a cable provider.
Discover Your Local Channels and Their Signal Strength
To find out which TV channels you can get over the air for free, we recommend visiting a site called TV Fool and using their
signal locator tool. Simply enter your address and click on “Find Local Channels”.
Give it a few moments to load the next page. Once it loads, you’ll
see what looks like a round diagram with various lines inside, as well
as a list of channels off to the right, highlighted in different colors.
It can be a bit daunting trying to figure out what it all means, but
the only thing you really need to pay the most attention to is the
circular diagram. The lines you see are in various lengths, and each
line represents a channel. The longer a line is and the closer it is to
the center of the bullseye, the better the signal is for that channel
based on your location.
The direction of the lines are important as well. The diagram’s cross
represents north, south, east, and west. As you can see from my diagram
above, most of the broadcast signals are coming from the northeast,
which means I should ideally place my antenna in the northeast corner of
my house so that I can get the best signal possible. (More on antenna
selection in a moment.)
From the list of channels on the right-hand side, you really only
need to focus on the distance of the broadcasts signals, which tells you
how far away they are.
Since many of the signals that I can get are fairly close to my
location (only 5-10 miles away), placement of my antenna isn’t super
critical. However, if your broadcast signals are farther away, you’ll
need to pay extra close attention to where and how you place your
antenna.
TV Fool gives you a rough idea on this by using colors to highlight
which channels you’ll easily receive and which ones would be more
difficult. Channels in green are channels that you could get with a
basic TV antenna, while channels highlighted in yellow and red will need
a more powerful antenna and strategic placement.
The Different Types of Antennas
Which type of antenna you purchase largely depends on the information
that you gathered from above diagram, and different antennas are
available depending on how far away you are from the broadcast signals.
Indoor vs. Outdoor Antennas
Not all TV antennas are weatherproof, and many cheaper ones are only
meant to be placed indoors. If broadcast signals are relatively easy to
come by in your area, then you’re probably fine getting an indoor
antenna.
If some of the broadcast signals are farther away, though, an indoor
antenna may not be powerful enough. For that, you’ll need an outdoor
antenna, built to take the grunt that mother nature provides, and reach
much farther. Outdoor antennas are almost always more reliable, though
they take a bit more work to set up.
Directional vs. Multi-Directional Antennas
You’ll also want to consider whether the antenna you get is
directional (also called uni-directional) or multi-directional (also
called omni-directional). As you can guess, directional antennas grab a
signal from a single direction, while multi-directional antennas can
fetch signals coming from any direction.
Multi-directional antennas are more convenient, but have a
significant downside: their range is usually much weaker than
directional antennas, which can put all of their power toward gain a
signal from a single direction. Multi-directional antennas can also
suffer from noise and interference coming from all directions, whereas a
directional antenna can block all that out.
Of course, a directional antenna will only work if the channels you
want are all in one direction. If they’re coming from different parts of
town, a directional antenna won’t work well for you.
VHF vs. UHF
Television broadcast signals are transmitted over two different
frequencies: Very High Frequency (VHF) and Ultra High Frequency (UHF),
so it’s important that the antenna you end up buying supports either or
both (ideally both).
If you go back to your TV Fool analysis, you can take a look at the
section below the list of channels, which will tell you what channels
use UHF and which ones use VHF.
You don’t need to know a whole lot about this, other than which
frequency is used the most by the channels that you can receive over the
air. If they’re mostly UHF, then you’ll want to be sure to buy an
antenna that can grab UHF signals. Most antennas can grab both VHF and
UHF channels anyway, but it’s good to check before you buy, just in
case.
A Note on Pre-Amplifiers
Other than the antenna itself, you also may need what’s called a
pre-amplifier, which is a small device that gets connected inline with
the antenna’s coaxial cable on its way to your television.
If the cable from the antenna to the TV is going to be any longer
than 50 feet or so, then you’ll need to get a pre-amplifier. The longer
the cable is, the weaker the signal gets by the time it reaches your
television, so using a pre-amp (like
this one) and installing it near the antenna inline with the cable will make sure that you don’t lose any signal strength.
However, make sure to check if your antenna already comes with a
pre-amp built in. Many outdoor antennas already do, since they know
you’ll likely need a long run of cable to make it to your television.
Our Recommended Antennas
If you’re looking for a basic indoor multi-directional antenna,
this 1byone indoor antenna ($13)
is one of the most popular indoor TV antennas on Amazon, thanks to its
25-mile range and measly price tag. If you just need a cheap, basic
antenna to place in a window and be done with it, that’s a good option.
It has a common flat design to it that many antenna makers use, so feel
free to go with another company if the price is better—The
Mohu Leaf ($40) is also very popular (I have one and it works great), and The Wirecutter recommends the
ClearStream Eclipse ($40,
amplified version for $60).
Indoor directional antennas aren’t as common, but they do exist.
This antenna from Terk ($60) is a popular option with a range of 45 miles. We’ve also used the 60-mile
ClearStream 2 ($90)
in the past with great results, though it’s a little big to be
considered “indoor” (even though it’s labeled as such). Still, on an
apartment balcony, we found it got all the channels in that direction
with great clarity.
If you want an outdoor multi-directional antenna, we use
this amplified 60-mile range model from 1byone ($70)
and it works great. There’s no need to point it in any specific
direction, so you have a lot more options as far as where you could
mount it on the outside of your house, which also helps since you need
to run power to it.
Outdoor directional antennas are extremely common, though, so you’ll find a lot of options in this area.
1byone’s outdoor directional antenna ($45)
has an 85-mile range, which has a farther reach than their
multi-directional model, but it’s also much larger. It also requires
that you plug it into a power source, since it’s amplified.
Again, there are lots of other antennas out there, but these are a
few popular, highly rated options (and a few we’ve tried ourselves with
good results). Every antenna will work a little differently depending on
your neighborhood and where you set it up, so you may have to try a
couple before you find the ideal one for you. Buy from somewhere with a
good return policy!
How to Hook Your Antenna Up to Your TV
Got your antenna? Great! Now it’s time to set it up and try it out.
You’ll first need to position the antenna in a good location (ideally
where it has the best line-of-sight with signal towers). Again, if you
get a very strong signal, a basic indoor antenna by your TV will
probably be good enough. Mounting it by the window will get you a better
signal, if you need it. (Don’t actually mount anything on your wall
until you’re happy with the signal you get, though. You may need to move
the antenna around to improve your signal and experiment with different
locations.)
If you need an outdoor antenna, though, it’ll take a bit more work to
install—you’ll likely have to use a ladder to climb up and mount it to
the roof or side of the house using the included hardware. If you aren’t
comfortable doing this, call a professional. (Check to see if your
house already has a roof antenna, too—many do!)
After you’ve found a good place for your antenna, connect it to your
television with the included coaxial cable. In the photo above, you can
see how we’ve attached the coaxial cable from our antenna to the antenna
input jack on our TV. And if your antenna is amplified, plug the
amplifier into a power source. Our antenna can be powered via USB, so we
plugged the USB cable that powers the amplification system into the
TV’s USB port.
Once it’s plugged in, head to your TV’s channel setup menu. Your TV
will need to scan for available channels, which should take just a few
minutes. When it’s done, you’ll be watching HD TV channels, you can cut
the cable cord for good. If you aren’t getting the best signal possible,
adjust the positioning and try scanning again—hopefully, with a bit of
tweaking, you’ll be watching all your local channels in crystal-clear
HD.
