21 dBi, 65°, 0-6°, Quad Port Antenna

CellMax offers the most compact Quad Port, 21 dBi, 65° antenna, 0-6° variable tilt, (1710-2170MHz) on the market, only 2,0m in length. Thanks to superior energy efficiency in the antenna, energy losses are close to zero, which maximizes gain while maintaining all radio pattern parameters intact. This includes fully maintained USLS throughout the full tilt range.

The technology used is patented by CellMax and has been developed to maximise the gain latent in the antenna. No intermodulation or other degradation from GSM-1800 in UMTS RX band

The QP Antenna from CellMax is the ultimate choice for:

  • Dual band sites GSM-1800/ UMTS 2100 or DCS/PCS.
  • Site sharing between different bands or operators.
  • GSM-1800 sites with 4 TRX’s in air combining , no hybrid losses.
  • Quadruple receiver diversity, (4 receivers in diversity configuration) with highest possible performance from excellent pattern control.
  • Soft boosting of 2 TRX’s (4 transmitters and 2 TRX’s with “bit shift” in time).
  • Compatible with any TMA configuration with no need for external diplexers.
  • Individual Remote Tilt control either from two separate MCU’s (one in each BTS) or from one central MCU offers full flexibility.

The patented feed network has also lead to improved performance on key parameters reducing interference in general.The technology provides highest possible efficiency in the antenna feed network, which is superior to traditional antennas that have inherent limitations in achieving ultra high gain.



Rosenberger acquires majority in CellMax

Rosenberger Hochfrequenztechnik GmbH & Co. KG, today announced that it has acquired a majority stake in CellMax


CellMax offers mobile operators to dramatically improve network performance. The CellMax antenna technology unveils significant energy and signal waste inherent in the traditional antenna.

The waste reduction from a CellMax antenna is so great that it provides the operator with dramatically improved network performance (more output power and less interference) and hence more revenues.

The high efficiency antenna technology from CellMax has set a new standard for network design around the world.
