    • Description:
    Microlab BK-21 series Wireless Local Area Network (WLAN) Injector is a filter diplexer for indoor. It links W-LAN designed to 802.11(b/g) with a coaxial distributed inbuilding cellular network or DAS. This gives W-LAN the benefit of the same controlled coverage as the DAS, eliminating many W-LAN uncertainties.

    To minimize the effects of the Injector to the DAS the inputs are well isolated and have minimal insertion loss.

    The W-LAN Injector has been designed using passive, proprietary techniques to ensure minimal loss and high reliability. Corner holes are provided for simple mounting to a surface or cable tray.
