RFS base station antenna

RFS has unveiled its family of high-performance Optmizer CELlite base station antennas.

The series centres on a slimline dual-polarised range designed to complement RFS’s vertically polarised CELlite variant, providing carriers with a stable and lightweight antenna solution.

It supports all services between 806 and 960 MHz.

Features include upper side lobe suppression of typically better than 18 dB across the entire frequency range, together with high gain, a six-degree downtilt and a front-to-back ratio of typically 28 dB.

The aim of the antenna is to assist carriers when solving the headache of supporting multiple standards and multiple frequencies.

The industry has moved on from the traditional tree-and-branch approach of base station installs, with minor base stations in rural areas parented onto primary base stations and then into the main carrier network.

The antenna suite features a robust micro stripline power feed system constructed from monolithic aluminium, in place of the traditional cabled feed system.

This, coupled with the antenna’s one-piece panel construction and a reduced number of weld joints, means the antennas are capable of supporting advanced passive intermodulation performance, a feature that assists carriers in maximising call quality and avoiding dropped calls.
