APPLICATION The Flamethrower Mini-Bridger (FTMB) station provides a multi-port 5-1000 MHz platform to support a family of plug-in amplifier modules and associated accessories. Used in bridger applications, the FTMB has two output ports with each port driven by its own power double hybrid. BENEFITS Flexible system design applications Simple set up Increased network reach 2 power double driven outputs Minimizes plug-in accessories Optional split outputs DISCONTINUED; REPLACED BY 870 MHz MINI-BRIDGER www.scientificatlanta.com 1 RF_FTMB 9.18.01
