Product Description

BK-261 In-line Diplexer allows efficient combining of CBRS and LTE-LAA bands with a coaxial distributed in-building cellular network or DAS. The unit has an extremely broad frequency range with minimal loss for maximum flexibility. This can provide the benefit of the same controlled coverage of the higher frequency services with the DAS.

The Diplexer has been designed to be small and lightweight, using passive, proprietary techniques to ensure minimal loss and very high reliability. A simple bracket and tapped holes are provided for simple mounting to a surface or cable tray.
