Drive Reach OTR is our most powerful multi-user, in-vehicle cell signal booster for semi-trucks. It’s designed to reach cell towers at distances up to 74% farther than the Drive 4G-X OTR. With its durable, redesigned omnidirectional OTR antenna, Drive Reach OTR stops dropped calls while improving voice quality, data speeds, streaming ability, and more while on the open road. Drive Reach OTR works on all U.S. carrier networks and is compatible with all phones and other cellular devices (including ELD and telematics) as it simultaneously supports multiple users. This booster kit comes with parts to accommodate multiple installation options including extra antennas and power supply to be able to transfer the booster between vehicles.
