Product Description

The new SureCall EZ-4G is an "Easy Install" booster kit. It supports 2G/3G/4G LTE across all US and Canadian carriers.

The EZ-4G does not require an outdoor antenna. It has only one cable and a combined exterior antenna and amplifier unit. The EZ-4G is ideal for customers living in apartments, rented accommodation, condos, shared offices or anyone who doesn’t have access to their attic or roof. Its “plug and play” design means it’s very easy to install, with a simple window set-up and no outside cabling.

The SureCall EZ-4G is FCC approved and offers coverage of 1-2 rooms. It supports multiple simultaneous users.

Amplifier and Built-In Outdoor Antenna

The combined outdoor antenna and amplifier is an attractively designed unit which needs to be positioned indoors beside a window which receives some existing signal. It can be attached directly to the window using the included mount. There is also an included stand so the unit can be freestanding. It is 13" in diameter.

Indoor Antenna

The indoor desktop antenna is a stylish indoor antenna that rebroadcasts the boosted signal from the combined amplifier/outside antenna unit. It needs to be positioned at least 20 feet (and ideally 30 feet) away from the amplifier unit for maximum coverage. This is to prevent oscillation (you can find a detailed explanation of how this works in our antenna guide).


SureCall warranties all of their amplifiers, antennas, and RF components for 3 years against any workmanship or material defects.
