Frequently Asked Questions

Why should I buy the Uniden UM50?

The Uniden UM50 works best in urban and suburban areas, for people who have long commutes or drive a vehicle in a service capacity. If you regularly conduct business or need entertainment on the road, the Uniden UM50 will reduce buffering and eliminate dropped calls by keeping you connected to your nearest towers. It is powerful enough to cover the entire vehicle in anything but the weakest signal situations.

The Uniden UM50 is Uniden’s primary signal booster for vehicles, including cars, SUVs, trucks, semi trucks, RVs, fleet vehicles, boats, yachts, and more. This is a 5G ready booster primarily operating on 4G LTE and 3G voice and data frequencies.

Please call us at 1-800-470-6777 for a free consultation and answers to any other questions you might have.

How does installation work?

Vehicle signal booster installation is simple:

  1. Place the outdoor antenna on top of your car/mount it to your truck.
  2. Place the cradle on your dashboard or attach it to an AC vent
  3. Plug power supply into car power supply.
  4. Enjoy your booster!
Where can I use this booster?

The Uniden UM50 will work in any vehicle or indoor location. It is designed for use while moving or in the interi of a vehicle, such as a car, SUV, truck, van, semi, boat, yacht, or schooner.

It is not designed for outdoor use.

How do I get the booster connected to my phone?

The Uniden UM50 amplifies the signal reaching your phone at the source, so your phone doesn’t need to “connect” to anything. It isn’t a WiFi router – if your phone can detect cellular signal, then it will pick up the amplified signal the booster emits. As long as it is in the vehicle, it should be receiving amplified cell service.

If all this sounds complicated, that’s because it can be. Call us at 1-800-470-6777 with any questions – toll free.

How can I determine the boost I’m getting?

Get the OpenSignal app if you have an iPhone, or the Network Cell Info Lite app for Android, and get reading your signal strength in standard dB (decibel) measurement. The closer to 0 your number, the stronger your signal.

What is the Return Policy?

All Uniden systems, including the UM50, can be returned within 90 days. It also comes with a 2 year warranty.
