This features two independent antennas with cross polarization.This feature doubles the wireless capacity over the same channels.The antenna is fed via two N-Female ports, one for +45° polarized and one for -45° polarized signals.

This feature makes these antennas ideal for polarization diversity systems.

Remote Electrial Tilt (RET) Components:

3G mobile systems based on CDMA technology have the "breathing effort" which requires more frequent adjustment of the antenna tilt angle than that of the 2G systems, to meet the periodic variance of the traffic.

Ameison has provided the full series of the Remote Electrical Tilt (RET) solutions, including the RET antennas, Antenna Control Unit (ACU), Portable Control Unit (PCU), Smart Bias Tee (SBT) and control cables, etc. They are fully interoperationabe with AISG V2.0 compliant RRU and Node-B, etc.

The tilt angle of the antenna can be accurately checked and adjusted remotely from the OMC center without climbing up the tower and shutting down the RF power, greatly reducing the workload of the network optimization.

Remote Electrical Tilt (RET) antenna systems are designed so that wireless providers can make adjustments remotely to their antenna systems.

The Antenna Interface Standards Group (AISG) has created specifications for the control interface for these types of systems.

Tips: Remote Control Unit(RCU) and AISG 2.0 connector 50M or longer 141 RET control cable can be matched if needed, manual adjustment or optional ACU for RET control.

With our RET system, operators can optimize their beam through tighter RF containment, precise pattern control, intermodulation suppression and real-time flexibility.

Our RET system enables you to make antenna adjustments from the office without costly site visits, tower climbs or network downtime.

Because you can improve network optimization in minutes — and in any weather — you can deliver better call quality and enjoy a higher level of customer satisfaction.

--Respond quickly to changing traffic needs

--Experience higher tilt possibility compared to mechanical tilt

--Reduces human error with accurate mechanical control

--No specialized manpower or equipment needed

--Ideal for isolated or difficult-to-access sites

Ameison's Base Station Antenna Series have covered the 790-2600MHz which containsall main-stream 2G/3G/4G mobile communication system, including GSM900, DCS1800,PCS1900,UMTS2100,TD-SCDMA and LTE2600, etc.

Our experienced international development team has successfully developed hundreds of high qualitied wideband, multi-band, electrical tilt and smart antennas, based on the highest technical standards and the strictest application environment grades in the industry, by using the advantage electromagnetic and mechanical simulation software, like Ansoft HFSS, CST Microwave Studio and Solidworks, etc.

All Ameison base station antennas are 100 percent production tested in an anechoic chamber for VSWR and IM for consistent, trouble-free performance in the field.

Each dual polarized antenna is also tested for isolation.
