Best Cell Phone Signal Booster for a Metal Building

When you live in a metal home, you could have issues getting a good cell phone signal. In some cases, you may only be able to get a signal outdoors, which isn’t very helpful. It is important that you are able to make calls inside and outside of your barndominium or metal building. A cell phone signal booster for a metal building is a great way to make sure your phone works. 

By getting a cell phone signal booster, you can make sure your phone is working in your home. By taking the signal from a separate antenna, it can give you complete coverage. However, there are a lot of signal boosters to choose from and they are all different. Knowing which cell phone signal booster for a metal building is best can help.  

What is a Cell Phone Signal Booster for a Metal Building?

A cell phone signal booster uses the outside signal from your service provider’s cell tower. Through an exterior antenna, it will amplify that signal inside your home and around it. You mount the antenna wherever you get the best possible coverage on or around your barndo. This will ensure that the signal is strong inside the home and that you are covered. 

A cell phone signal booster is essential because you need to have at least three bars for good service. If you can’t get that inside your home, you won’t be able to depend on your phone. If there is an emergency, you will be glad you have a strong, robust signal inside. You don’t want to have to go outside just to be able to make a phone call. 

Why Your Cell Signal Doesn’t Work In Your Metal Building

Nearly anything can affect cell phone signal strength as it traverses from your nearest cell tower to your cell phone, tablet, or laptop. One of the toughest materials for cell signal are all kinds of metals, including aluminum, copper, steel, iron, and more. It can really hurt the cell signal trying to get past the material. If you can imagine a barndominium like the one pictured (which are typically made of almost all metal), this is likely one of the worst home materials for your cellular device.

How To Boost Cell Signal In Your Metal Building

Cell phone signals can be significantly weakened when trying to penetrate through metal buildings, causing problems with dropped calls, slow data speeds, and poor call quality. Fortunately, there are a few steps you can take to improve your cell phone signal while in a metal building.

One effective solution (our top recommendation is below) is to install a signal booster or repeater. These devices work by capturing the weak signal from outside the building, amplifying it, and then broadcasting the stronger signal inside. They can be a bit pricey, but they are highly effective and can significantly improve your signal strength.

Another option is to try using a cell phone signal booster app. While not as effective as a dedicated signal booster, these apps can help to enhance your signal by optimizing your phone’s settings and using software algorithms to amplify your signal. However, they can be hit-or-miss, and the effectiveness of the app will depend on the quality of your phone’s hardware and software.

Lastly, you can try moving closer to a window or outside of the building to improve your signal strength. This is especially effective if you are in a low-lying area where signals struggle to penetrate buildings. Additionally, you can try switching carriers, as some networks may perform better than others in certain areas or buildings.

Why Use a Cell Phone Signal Booster for a Metal Building?

Barndominiums or metal buildings have steel walls and siding as well as steel girders and beams. In addition, most barndominiums will ALSO have a metal roof. Having a metal roof can also cause issues with cell phone signal reception, as metal is known to block radio waves. You may not be able to get service inside due to the heavy, shielding materials your home is made of. Also, most barndominiums are built in rural areas that may be far away from the closest cell tower. This can cause all kinds of problems for both convenience and safety. Imagine not being able to call 911 in an emergency because you don’t get cell reception. Not a good scenario!

A cell phone signal booster will be the cheapest way to get cell phone signal in a metal building. We’ve heard stories of people going to battle with their cell phone provider – not worth it in our opinion! Just get a device that repeats the existing signal as it’s easy and it just plain works.

The cell phone signal booster for a metal building you choose will depend on several factors. If you don’t get a very good signal outside, you may need a more powerful booster. If your metal building or barndominium is exceptionally large, you may also need a stronger one for coverage. Knowing which cell phone signal booster for a metal building is best for these situations can help.
