ILB-150-33W40 VHF High Performances In-Line Booster
The EMTS LMR/PMR In-Line Booster (ILB) offers a robust solution to mitigate insertion losses from passive components and transmission losses in feeder cables, particularly in indoor distribution systems and tunnel coverage scenarios. By deploying the ILB, LMR/PMR operators can effectively expand the service area of a base station, offsetting feeder losses through signal amplification along coaxial or leaky cables utilizing Advanced Bi-Directional Technology.
The ILB's lightweight design, straightforward installation process, and user-friendly GUI enhance ease of deployment and operation. This solution is a cost-effective and practical option for improving signal coverage in areas with limited LMR/PMR network reach, such as buildings, shopping centers, airports, and tunnels. The ILB seamlessly integrates into passive Distributed Antenna Systems (DAS) via coaxial cable connections, offering a wide range of configuration options to meet diverse customer requirements.
