Cambium's RDH4510B is a dual-polarised High Performance (HP) parabolic dish antenna manufactured by RadioWaves. The 1.2 metre (4 ft) diameter antenna provides a nominal peak gain of 34.7 dBi from 5250 to 5850 MHz, and capable of operation across the full 5 GHz band from 4900 to 6000 MHz with only a minor degradation in performance.

With it's integrated radome, the 1.2 metre diameter RDH4510B is used in long distance point to point, providing connectivity beyond 50 kilometres, and considerably further in many regulatory environments.

The HP High Performance Series by RadioWaves offers a full line of high performance parabolic antennas engineered to provide ETSI class 2/3 radiation pattern conformance as well as excellent gain.

RadioWaves field-proven pre-assembled antennas and robust pole mounts ensure “set and forget” installation with minimal post-installation maintenance. The included radome ensures robust and reliable performance under the most challenging conditions.

RDH4510B has been selected by Cambium for pairing with its PTP 450i, 550, and 670 series 5 GHz point-to-point radios due to its known and reliable performance. To ensure PTP radios can be accurately diagnosed and supported, deviation from manufacturer specified antennas is not recommended.

All RadioWaves antennas are provided with a 7 year manufacturer warranty.
