About This Part
The Kathrein 78211401 is a high-performance triple-band combiner, serving as a critical passive RF component within modern wireless infrastructure. Its primary function is to combine three separate radio frequency input signals, each operating within a distinct frequency band, into a single output signal. This ingenious design allows for the use of a single antenna and feeder line, significantly reducing cabling complexity, tower loading, and overall site footprint. Key technical characteristics include exceptionally low insertion loss to minimize signal degradation, high isolation between input ports to prevent inter-band interference, and robust power handling capabilities suitable for multi-operator or multi-technology deployments. Typically housed in a rugged, weather-resistant enclosure for outdoor installation, it features industry-standard RF connectors (e.g., 7/16 DIN) to ensure reliable connectivity within demanding environmental conditions, optimizing RF path efficiency and spectral utilization. These Kathrein triple-band combiners are deployed extensively at cellular base station sites, including macro cells, small cells, and rooftop installations, where multiple frequency bands (e.g., those allocated for 2G, 3G, 4G, and 5G services) need to share common antenna infrastructure. They are indispensable for mobile network operators globally, enabling them to expand network capacity and introduce new technologies without requiring additional antenna installations or extensive site modifications. By consolidating multiple RF paths into one, the Part Number 78211401 effectively solves challenges related to site space limitations, reduces the visual impact of cellular sites, and significantly lowers both capital expenditure (CAPEX) on cabling and operational expenditure (OPEX) associated with site maintenance and energy consumption. This component is vital for facilitating network modernization and densification strategies. In the dynamic telecommunications landscape, acquiring new infrastructure can represent a substantial investment. Revo Distribution Limited addresses this challenge by offering high-quality used and refurbished units of the Kathrein 78211401 triple-band combiner to B2B clients worldwide.
