Repeater and Microcell Antenna

Yagi antennas- adapted for outdoor sectorized point-to-point coverage applications. Can also be used as a repeater donor antenna with highly directional antenna arrays.

Parabolic Antennas – feature high gain and good F/B ratio which make them best suited as donor antennas for repeater cells.

Corner Reflector Antennas- use log-periodic elements and are designed with light weight slotted reflectors that feature very high F/B ratio and narrow horizontal beamwidth. This minimizes interference from adjacent cells when used as a repeater donor antenna.

Base Station Antennas

Directional Panel Antennas – include single, dual and multi-band with vertical or cross-polarized, and fixed or variable electrical tilt. These antennas are cost-effective and come with beam-shaped features to improve the coverage for urban and sub-urban areas, while minimizing spillage outside of cell radius.

Tri-sector Directional Antennas – combine three wide band antennas under a single radome hence reduce visual impact of antennas and minimize sitting issues such as site approval, space limitations, and aesthetics issues. Maximizes the coverage footprint whilst minimizing site space occupied by the 3- sector antenna system.

Omni Directional Antennas – aesthetically designed and best suited for providing coverage in remote areas where capacity is relatively low, such as in small towns and rural areas.

Indoor antennas

Indoor antennas feature broadband design from 670MHz up to 2700MHz. They can be camouflaged and/or aesthetically pleasing for indoor installations in a distributed antenna system. They are compact in size, light-weight and easy to install.

Camouflage Antenna

Camouflage antenna solution for mobile operators that adopt integrated design and additional radome approach to achieve camouflage effect on antenna, feeder, pole as well as equipment. Solutions cover all major telecom networks such as GSM, CDMA, TD-SCDMA and WCDMA and suitable for BTS, repeater and IBS system application. So far, more than 10 thousand of Comba’s camouflage antennas are being deployed worldwide, effectively solving site selection/network rollout problems for operators and make an outstanding contribution to a more eco-friendly society.

Camouflage antennas are widely used in:

Outdoor marco coverage ground/roof solution

Outdoor marco coverage building wall solution

Indoor coverage solution

Residental area coverage solution

Multi-Band Combiner / POI

From antenna to base station, Comba offers a complete suite of filters, combiners, power splitters and couplers for Common Antenna System (CAS) and RF network optimization.
Multi-Band Combiner or POI (Point-Of-Interface) is designed for cost effective antenna sharing solution for outdoor and indoor applications. The combiner is customized to combine specific frequency spectrums without incurring high insertion loss compared with using conventional couplers and power dividers. This allows Operators to integrate their frequencies into a common antenna system with greater ease and efficiency. Wide range of combiner product includes diplexer, triplexer, and quad- band combiner for 2G /3G /LTE system.

Comba POI is built with high quality filters that handle high input power, good isolation between bands and low insertion loss. This product is widely used in places such as convention centers, exhibition halls, airports, underground tunnels and other large buildings where common antenna system are usually deployed.

Passive components

Our range of passive components is designed using high performance filter to provide reliable and cost effective solutions for both indoor and outdoor applications. Such couplers and power dividers are commonly used in in-building solutions and for co-location of antenna.

  • Wideband design to enable feeder sharing between multi systems
  • High isolation minimizes interference
  • Good PIM performance
  • High power handling and low loss maximizes system performance
  • Outdoor combiner comes with optional DC bypass for use with Tower Mounted Amplifier or AISG line devices and is available as a single unit or double unit

In addition, Comba also produces interference rejection filters. These filters can be used at the transmission or the receiver end for:

  • Increasing isolation of transmitters
  • Reducing 3rd Order Interference (IM3) and side-band noise to prevent receiver blocking
  • Reducing spurious emissions
