UHF 100MHz 400MHz 800MHz Digital TV Cellular Repeater

Specifications of Digital TV RF Repeater Model: BT-BA43D The Digital TV RF Repeater (RFR) is designed to provide a more cost-effective solution than adding a new digital TV transmitter to improve network coverage and signal quality of digital TV. And its easy installation and maintenance can help carrier get fast return. The repeater is working as a relay between the TV transmitter and receivers during the broadcasting of digital TV signal. It receives low-power TV signal from the TV transmitter via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna to the weak/blind coverage area. The enhancer can amplify the signal within the customized band. Features Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corroding No interference to BTS by adopting linear amplifier with high gain and low noise Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink USB port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise repeater's working status and download operational parameters to the repeater Applications To expand signal coverage or fill signal blind area where signal is weak or unavailable.
