Cel-Fi GO G51 is a robust 5G repeater offering up to 100 dB of signal boost to improve 3G, 4G and 5G cellular signals in large residential and medium-sized commercial spaces. It can cover up to 2000 sq. meters of area making is the best 4G & 5G coverage improvement solution. Approved by ACMA for use on Telstra, Optus and Vodafone networks, Cel-Fi G51 is ideal for areas with access to a 5G NR-3500 signal to maximize 5G coverage indoors, enhance data speed and reduce dropped calls.
Our DIY included low-loss Pulse 400 (LMR400) cables & connectors. Due to their high-quality standard, you can draw maximum performance out of the Cel-Fi G51 unit. Pulse 400 is a very flexible cable and makes installation very easy.
Note: G51 has a relay bandwidth of 100 MHz + 20 MHz and supports up to two bands. 100 MHz is here is for 5G-NR and 20 MHz for 4G-LTE (typical 3GPP NSA configuration). If there is no 5G-NR to improve, the relay bandwidth shrinks to a mere 20 MHz. Hence in a scenario of no 5G coverage on 3500 MHz band in your area, it's recommended to consider Cel-Fi G41 model instead.
