Product Details

The SureCall EZ 4G is currently backordered and expected to ship in 3 weeks.

The SureCall EZ 4G Signal Booster Kit is designed to be very easy to install and look great when installed in your home or office. The booster uses a window mount unit, that can be either mounted directly to the window or sit in the window on a sill, and a small desktop antenna connected by a coax cable for boosting signal. Setup takes only a few minutes and the unit automatically adjusts itself for maximum performance.

Please Note: For maximum performance, you should have 30+ ft of separation between the window unit and the inside antenna.

Recommended For

The SureCall EZ 4G signal booster kit is recommended for situations where you're not able to mount an antenna outside of the home or office that requires boosted signal, and only need to boost signal in a small area inside of the building, such as in a single room, or for very weak outside signals, a desk, table or other similarly sized area. If there is a strong signal at in the location where you mount the window unit, the EZ 4G may be able to fill up to an entire room with boosted signal.

How it Works

How the SureCall EZ 4G works

The main unit of the SureCall EZ 4G is designed to be located in the window of the building that receives the best outside signal. It can either be afixed directly to the glass, using the included adhesive, or sit on the window sill, using the included stand. The window unit will receive the outside cell signal, amplify it, and then pass it along the included cable to the inside desktop antenna, which should be located in the area of the building that needs boosted signal. The system will automatically analyze the signal environment, and adjust itself to provide maximum boosting power.

The entire process also works in reverse, so you get a strong and reliable connection back to your carrier.

Estimated Inside Coverage

The strength of your existing outside signal, measured in the location where you plan to mount the outside antenna, has a direct impact on the amount of inside coverage you'll get from a signal booster. The table below shows how much coverage you may get depending on your outside signal strength:

Existing Outside Signal Strength Estimated Inside Coverage
Strong (5 Bars) Up to 1,200 sq ft
Medium (3-4 Bars) Up to 750 sq ft
Weak (1-2 Bars) Up to 100 sq ft
None (0 Bars) No Coverage

Please Note: It is important to remember that there are many factors that impact the size of the inside coverage area, so actual results may vary from these estimates.

Additional Coverage

If you need more coverage than one system will provide due to a weak outside signal, you can install multiple SureCall EZ 4G systems in your home or business. Please contact us for assistance with mapping out the ideal location for each system.

If you need more coverage than the SureCall EZ 4G will provide, and you're able to figure out a way to mount an antenna outside on the roof, then the SureCall Flare is going to be a better choice for you. It has a more powerful amplifier and an external antenna to provide more inside coverage with the same strength outdoor signal. Please contact us if you have any questions or would like more information about this system.

Installation Overview

The installation of the SureCall EZ 4G is very easy and should only take you a few minutes. Follow these simple instructions and you should be boosting signal in no time:

  1. First, decide if you're going to use the double sided tape to stick the window unit directly to the window or if you're going to use the included stand (in which case, you'll need to attach the stand to the window unit). Once you've decided, then locate the window unit in the window where you get the best initial cell signal.
  2. Next, connect the included 50 ft RG-6 cable to the cable connector that is connected to the window unit, and then run to the location where you plan to locate the inside desktop antenna.
  3. Connect the desktop antenna and locate it on a desk or table for best coverage.
  4. Connect the AC adapter to the other connector coming off the window unit, and plug into a standard wall outlet.
  5. The SureCall EZ 4G will automatically adjust to the current setup and create the best possible coverage area inside of the home or office for you.

Please note: For maximum coverage, you should have 30+ feet of separation between the window unit and desktop antenna.
