MI-146

TMA TWIN 800/900 MHZ


Designed to be deployed in collocated 800 and 900 systems, the Kaelus MI-146 enhances cell uplink coverage in 800 and 900 through improved system noise figure, thereby saving operational and capital expenditure.

FEATURES

  • Improved base station sensitivity through gain in the 800, 900 uplink
  • Excellent noise figure performance
  • Full AISG operation and RET antenna support, AISG2.0 compatible
  • Small and light for minimum visual impact
