Introducing RFI’s 800MHz Corporate Collinear Range

Posted on

RFI is excited to introduce our leading range of 800MHz Corporate Collinears into the Asia Pacific Region, expanding our extensive base station antenna offering for our APAC customers.

The 800MHz Corporate Collinear series is being launched into Asia due to their technical characteristics being ideally suited to Public safety, utilities and transport solutions in the region. This includes applications that require wide bandwidth, higher power and more channels. The Corporate range’s PIM and PIP ratings plus greater pattern control enabling more predictable coverage from modeling through to implementation/rollout.

The 800MHz corporate series is a complete offering including 3dBd, 6dBd, 8dBd and 10.5dBd alternatives, in downtilt variants with up to 5° of downtilt.

These robust, high-powered antennas cover the frequency range of 746-870MHz, and are a great replacement for traditional exposed dipole array antennas, packaged in a low profile fiberglass radome, and field invertible mounting capability (0° downtilt variants only). This preferred form factor provides a reduction in wind loading, ice loading and tower loading when compared to exposed dipole array configurations.

 

Key Features


  • High power, high gain and lower loss
  • Maximised gain, 3dBd, 6dBd, 8dBd and 10.5dBd options
  • Extraordinary bandwidth characteristics
  • Superior pattern control
  • Improved manufacturability and repeatability
  • -150 dBc PIM rated
  • 25KW PIP rating
  • Available with up to 5° of downtilt
  • Field Invertible (excludes tilt variants)
  • Elements directly grounded for improved stability and reduction of static precipitation

 

Applications


RFI supplied the CC807 corporate collinear antennas into a wind farm project in the Baltic Sea. Typically these systems would use TETRA for voice and WiMAX for data, but this particular project has utilized LTE in place of TETRA & WiMAX.

RFI’s CC807 corporate collinear antennas have been employed on the offshore installation vessels, for their high strength, low profile construction and omnidirectional broadband coverage. Covering 746-870MHz band, RFI’s CC807 series antennas have been a great success in this LTE application.

 

RFI’s Corporate Technology


Performance

The true corporate feed design maintains full pattern stability over the broad operating bandwidth, similar performance only to that previously offered by exposed dipole configurations. RFI’s new corporate collinear arrays offer greater flexibility when considering site design and installation, combine more channels with more accurate pattern control, and no beam tilt cross the band. RFI’s corporate antenna range has been designed with an exceptional power rating of 500W across the band as well as a Peak Instantaneous Power (PIP) rating of 25kW to cater for the peak voltage levels present in large multi-carrier combining environments. RFI’s refined design processes and proven construction methods achieve a PIM rating of –150dBc, further ensuring performance is maintained for the service life of the antenna.

Corporate Structure

The unique corporate phasing system employed within this antenna ensures excellent pattern and phase control. This coupled with precision element reproduction and placement, produces exceptional bandwidth, offers lower loss, maximises gain and ensures PIM and PIP rated electrical performance throughout the lifetime of the antenna.

Corporate Design

RFI has incorporated its patented flexible PCB technology into the design of its corporate arrays to ensure repeatability and performance of the elements every time. The dipoles are grounded directly to a brass support tube, and onto the lightning spike at the top of the radome providing a robust finish with exceptional lightning protection, better stability and a reduction of static precipitation noise.

 

The Range


RFI’s 800 MHz range covers 746-870MHz with various gain and Downtilt options.
