Can You Install a Signal Booster in the Attic?

Can You Install a Signal Booster in the Attic?

When assembling a residential signal booster, many guides or instructions will tell you to place the external antenna on the roof. Installing it outside puts distance between the internal and external antennas. However, many homeowners wonder if they can install a signal booster in the attic. SureCall Boosters is here to explain the mechanics and why this may be the right choice.

Can You Install the External Antenna Inside?

If you're looking for a quick answer, you can! It's not uncommon for homeowners to place the external antenna up against the rafters of the attic and aim it toward the nearest cell tower. However, you’ll need to prepare for some extra work that comes with this setup.

Why Install Indoors?

You may choose to install a signal booster antenna in your attic rather than on the roof for many reasons. Some of the most common reasons are that the roof is difficult to climb or entirely inaccessible. Some residents may take weather into consideration and not want to expose the antenna to harsh sunlight, pouring rain, or freezing snowstorms.

Common Problems To Avoid

Now that you know you can install a signal booster in the attic, you may need to work around some common issues. Since your antenna is indoors, the rafters of your attic and walls of your home may interfere with the signal. An indoor setup may also limit the placement options of your interior antenna; it’s best to avoid a feedback loop. Still, you can create a strong, reliable signal, but you may not get a cellular boost in the exact room you were hoping for with the antenna on the roof.

Many experts advise installing your antenna on the roof whenever possible, but you can still have a stable signal if it’s in the attic.
