Cellcomm manufacture and supplies various types for antennas which are ideal for indoor and outdoor applications. Quality and innovative designs are the speciality of Cellcomm antennas. Beam width and polarizations can be customized based on customer demands. Antennas are available for specific technologies like TETRA, CDMA, GSM, WCDMA, Wi-Fi, WiMAX, LTE and for wideband as well.
Types of antennas include:
Power Divider and Power Couplers
Power dividers (splitter) and Power couplers are passive devices used in the field of radio technology. Their applications include indoor and outdoor coverage enhancement solutions and distributed antenna system.
Power divider and Power couplers are designed with high quality in terms of minimum insertion loss, isolation, power handling and directivity to achieve better system performance. Power dividers and couplers are available in different range of frequencies starting from 380 MHz to 6GHz.

Feeder and Connectors
The connectivity from the transmitter to antenna is through RF feeders and connectors, which is essential for radio communication. Design and quality is important in terms of minimum losses, flexibility and types of dielectric material. Cellcomm provides different types of RF feeders which can be used based on the application and frequencies.
Point Of Interface
Point-of-Interface (POI) units combine multiple wireless communication systems to share a common distributed antenna system. POI consists of high quality combiners and duplex filters to achieve high system performance. POI is designed to use for all existing mobile technologies such as CDMA, GSM, WCDMA, Wi-Fi, & LTE. The POI equipment shall be one of the key components in the IBS project when it comes multi-operators using several different wireless communication systems. Key features of Cellcomm POI are very less insertion loss, good isolation between the bands and negligible passive intermodulation products.
Attenuators and Terminators
Attenuators and Terminators are passive devices used to control or terminate the RF radiating power. The products are available in different models and power handling capabilities based on the design requirements.
Cellcomm range of combiners provide compact and cost effective solutions for combining different technologies in a common output port or multiple output ports. The special design provides excellent inter-band isolation, low insertion loss and good intermodulation performance. Combiners can be customized based on the requirements and are available in different combination of inputs, technologies, outputs and power handling capabilities.
Cellcomm designs a wide range of filters suitable for different application in radio frequency band between 800 to 2700 MHz. Latest design techniques provide compact design featuring quality and high performance filters. Filters can be customized to meet the specific band width requirements and can be silver plated to improve the intermod performance and reduce the insertion loss.
