Outdoor Repeater DCS1800mhz Network Output 10watts
This big repeater can allow people to use it to improve the indoor voice service in a building by installing enough indoor antennas, the maximum coverage of this repeater is 2000 square meters in theory, but the preconditon is the outdoor signal received by the powerful outdoor antenna is strong, if the outdoor signal is poor, the acutal indoor coverage will be less accordingly, and it is not recommended to install multiple indoor antennas while the outdoor signal strength is poor.
Applications
To expand signal coverage or fill signal blink area where signal is weak or unavailable
Outdoor :Airports ,tourism regions, folf courses, tunnels, factories ,mining districts ,villages ;
Indoor :Hotels ,exhibition centers ,basements ,shipping malls , offices ,parking lots ;
