Multi - System Cell Phone Base Station Mobile Tower Radiation Safe Distance

Multimode antenna satisfies 3 operators’ FDD+TDD multiple network co-building, or a single operator’s ‘2G+3G+4G’ multimode shared station requirement. Once driver and controller are connected, it could realize remote control of antenna coverage area at background. Currently, shared antenna installation space, multimode and miniature antenna have become customers’ favors.

Product feature:

Multi-system base station antenna: Multimode antenna satisfies 3 operators’ FDD+TDD multiple network co-building, or a single operator’s ‘2G+3G+4G’ multimode shared station requirement. Once driver and controller are connected, it could realize remote control of antenna coverage area at background. Currently, shared antenna installation space, multimode and miniature antenna have become customers’ favors. Multi-mode antenna saves 30% cost than several single mode antennas which also saves the tower’s load-bearing.
