Band n78 uses time division duplexing, which substantially changes the rooftop donor antenna requirement compared with a G41. We plan the 5G donor design at survey.
Source and accuracy
Specifications are taken from the Nextivity CEL-FI GO G51 data sheet, EMEA/APAC (PDF, Rev26-0909) (opens in a new tab), checked 7 November 2026. Values the manufacturer does not state are left out rather than estimated.
- Band support depends on the kit number. On the ACMA exempt repeater list (checked 11 November 2026), the GO G51 is listed for Telstra only; we confirm each carrier's requirements per project.
Suited to
- Adding 5G to a Proeye repeater hub
- One carrier per module
- Small to medium-sized buildings
