  • Test: RFCOM conducts a complete inspection of each technical specification and tests each assembly for PIM, VSWR, etc.
  • ROHS compliant
  • Lifetime warranty: We guarantee the quality of our products with our lifetime warranty.

Co-Siting Combiner Questions & Answers

A co-siting combiner is a passive RF device used to combine or separate multiple frequency bands so several operators, radios, or services can share antenna feeders or tower infrastructure while maintaining proper isolation and RF performance.

Co-siting combiners are commonly used in BTS tower sites, rooftop sites, tower sharing projects, neutral host infrastructure, multi-band antenna systems, and RF upgrade projects where different bands need to coexist on shared feeder or antenna systems.

RFCOM supplies diplexers, triplexers, quadplexers, pentaplexers, hexaplexers, and customized multi-band co-siting combiners for telecom infrastructure projects.

Low PIM performance is important because co-siting systems often carry high-power multi-band signals. Poor PIM can create uplink interference, reduce network quality, and affect user experience. Low PIM combiners help maintain cleaner RF performance in shared infrastructure.

Yes. Co-siting combiners can be used in multi-operator and tower sharing environments when the frequency bands, isolation requirements, power handling, connector types, and installation conditions are properly specified.

The key information includes frequency bands, number of ports, power rating, connector type, insertion loss target, isolation requirement, PIM specification, indoor or outdoor use, IP rating, and mechanical installation requirements.

Yes. RFCOM can support customized co-siting combiners based on required frequency bands, port configuration, connector type, PIM level, power handling, environmental rating, and project-specific RF layout.
