8 / 2 Point of Interface POI / Multi-Band Combiner
Product Instructions:
Point of interface (POI) is a multi-combining system for Base station and DAS.
It combines several mobile operators(BTS or DAS systems) into just two output distributed antenna.
This is cost-effective measure of realizing the coverage by signals from multi-networks.
Product Features:
1. High Performance and high reliability
2. Good isolation, good power handling ability
3. Multi band Support.
4. Cost effective antenna sharing solution for outdoor and indoor applications
5. Easy installation.
Technical Specifications:
