1. Point Of Interface Multi Band Combiner

Description

Point of interface (POI) is a platform for multi-combining system for Basestation and DAS

It combines several mobile carriers(operators) BTS or DAS system two or four

output port(Comport) for distributed antenna system.

At the same time, it distributes the different uplink signals to their each system,

realizing multi-band and multi-signal combination and using simple two or four

Com Antenna portsThis is a feasible and efficient measure of realizing the coverage by signals

from multi-networks.

Key Features

High Performance and high reliability

Cost effective antenna sharing solution for outdoor and indoor applications

19 inch Rack Type.

Effective in time and installation as it easy and fast.

Support building esthetical aspect by reducing number of indoor antenna.

Multi band Support.

Good isolation good power handling ability and excellent IMD.
