FM直放站FR-100 CE
Product Description
The FM Repeater is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve signal coverage in FM system. And its easy installation and maintenance.
The repeater is working as a relay between the BTS and terminals. It receives the low-power signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna to the weak/blind coverage area.
Features
Ø ALC technology used to provide auto amplitude fixing.
Ø Adopting filter with highly selectivity and low insertion loss eliminates interference between downlink
Ø Modules structure, dual-port design, and built-in power supply, easy for maintenance and installation;
Applications
To expand signal coverage or fill signal blind area where FM signal is weak or unavailable.
Ø Outdoor: Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages
Ø Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots
