HiBoost SLD+ Commercial Signal Booster

Boost your bars.

The HiBoost SLD+ industrial cell phone booster increases voice, text, and 4G LTE data for all North American cell carriers, including AT&T, Verizon, Sprint and T-Mobile. It greatly enhances 4G, LTE, and 3G cell service for all your wireless devices (smartphones, notebooks, hotspots, etc.). Furthermore, it works regardless of phone model (iPhone, Android, Samsung Galaxy, etc), and is 5G ready.

The HiBoost SLD+ is a fantastic option for large buildings and commercial spaces, capable of boosting the signal of any carrier by up to +80 dB of gain across a coverage area of up to 65,000 sq ft.

We offer several configurations for the HiBoost SLD+. In general, if your area has strong outside signal, an omni antenna should work for you. If the signal outside your building is weak, go for a yagi antenna. Dome antennas are best placed on a ceiling and radiate signal outward in all directions, so they’re best placed on the ceiling in the center of a large room. Panel antennas shoot signal outward, so they’re best placed on a wall. Choose the antenna configuration that’s best for your situation - if you have any questions, feel free to call us at 1-800-969-8189 for a free consultation.
