NEW Kaelus Quad Band Combiner 700/850/1900/AWS DC Switch - QBC0002F2V51-1

Product Overview This is a brand new KAELUS QBC0002F2V51-1 Quad Band Combiner / Quadruplexer. Excess inventory from a company no longer in business. Comes new in original OEM sealed packaging. Perfect for telecom infrastructure upgrades, tower installations, or spare parts inventory.

Intended Applications Designed to combine 700 MHz, 850 MHz, 1900 MHz (PCS), and AWS bands onto a single feeder cable. Saves significant CAPEX and OPEX by reducing the number of feeders, antennas, and tower components needed. Ideal for macro cell sites, antenna sharing, multi-tech BTS deployments, and field-configurable DC/AISG routing in wireless networks. AWS 3 and 4 ready. Suitable for outdoor (pole/wall mount) or indoor use.
