Uhf Walkie Talkie Power Amplifier Long Distance High Output Power 20w 850mhz 900mhz 1800mhz Gsm Rep

Outdoor mobile signal booster 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, thesub-band and channels can be easily tuned by software to adapt tothe 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
