Nextivity CEL-FI ROAM R41 Smart Mobile Repeater
The Nextivity CEL-FI ROAM R41 Smart Mobile Repeater is a self-contained signal booster designed to improve 3G, 4G and 5G reception in vehicles, RVs and boats. Powered from a 12 V DC source and managed via Bluetooth using the WAVE App, it delivers up to 100 dB of system gain across eight cellular bands (including 700 MHz, 800 MHz, 1800 MHz, 2100 MHz and 2600 MHz). With a compact footprint of 170 × 79 × 43 mm and a sub-500 g weight, installation takes only minutes and supports dynamic spectrum sharing for uninterrupted voice, text and streaming on the move.
The ROAM R41 series is offered in multiple kit configurations to suit different mounting and antenna-cable requirements, from basic vehicle setups to marine-grade installations. All versions share the same core repeater hardware and power consumption of less than 18 W, but vary in connector types, cable lengths and bracket options so installers can choose the package that best matches their application. This makes it particularly useful for fleet operators, field technicians and anyone who relies on dependable mobile connectivity beyond fixed-site coverage.
