Outdoor mobile DMR UHF VHF radio Fiber Optical repeater amplifier
This digital radio repeater is an outdoor wireless booster with heavy duty weather proof design. It can transmit and extend cellular signal to longer range. With SDR technology, the sub-band and channels can be easily tuned by software to adapt to the operators' requirement without any change on the hardware. It provides cell coverage for 2G(900MHZ), 3G(2100MHZ), 4G(1800MHZ) networks in the areas with poor or no signal at all. 37dBm, 40dBm, 43dBm are available.
Description
The VHF fiber optical repeater amplifier is applied to VHF interphone communication system and trunking communication system signal coverage extension. It is also known as “VHF Fiber Optic BDA”.

Application
Fiber Optical Repeater amplifier is suitable for installation in place of laying fiber optic cable, and fiber optic cable distance should not exceed 10km.
Outdoor: Airports, Golf Courses, Tourism Regions, Villages, Highway, Tunnels, Mining Districts etc.
Indoor: Hotels, Exhibition Centers, Shopping Malls, Gymnasium, Basements, Offices, Factory, Hospital,Entertainment, Packing Lots etc.
Wireless-Access Fiber Optical Repeater: Receives BTS signal via a Donor Antenna (applicable when no fiber optic cable connecting to the BTS).It can be sorted into 2 sub-categories: Band-Selective and Channel-Selective.
