To escape the noise, the C5x lets you take advantage of both 4.9 GHz public safety applications and licensed frequencies up to 6.4 GHz, where allowed by local regulations. The custom-designed N5-X modular antennas are specifically optimized for C5x extended frequency support.
The C5x, with its die-cast aluminum metal enclosure, dual-pole mounts, and industrial-grade, twist-on antenna options, is optimized to reduce noise, withstand the outdoor elements and stay mounted in extreme weather.
Can the C5x base radio at 8 dBi be used without an antenna?
Yes. You can use the base C5x 8 dBi radio without an antenna for short-distance links. Please remove the locking screw from the twist-on screws to serve as a drain hole.
Do I have to install a feature key when initially unlocking the C5x?
No. As of March 1, 2019, feature keys are no longer necessary or available. Out of the box, the C5x can be used to its full potential — speeds of up to 700 Mbps in PTMP or PTP mode.
