40dBm High Performances In-Line Booster

Download Datasheet (PDF)

The EMTS LMR/PMR In Line Booster (ILB) provides an excellent solution to the problem of insertion loss of passive components and transmission losses of feeder cables for Indoor Distributions or Tunnel Coverage. Using the ILB the LMR/DMR operator can easily expand a base station’s service area by compensation for feeder losses. The ILB amplifies the signals on the coax cables or leaky cables by using Advanced Bi-Directional Technology. Easy installation, lightweight design, and very friendly GUI make our ILB easy to use and install. The EMTS ILB is a cost-effective and practical solution for extending signal coverage inside buildings, shopping malls, airports, and tunnels where the LMR/DMR networks have poor coverage. The ILB is used to extend the coverage area in a passive distribution antenna system (DAS) connected by coaxial cables.

needs for Wireless Networks. EMTS ILB provides a wide range of configurations to address different customer requirements.
