MI-149

TMA TWIN 1800/2600


Designed to be deployed in collocated 1800 and 2600 systems, the Kaelus MI-149 enhances cell uplink coverage in 1800 and 2600 through improved system noise figure, thereby saving operational and capital expenditure.

FEATURES

  • Improved base station sensitivity through gain in the 1800 and 2600 uplink
  • Internal diplexing on the antenna port of 1800,2600 bands: 2 Antenna ports
  • Excellent noise figure performance
  • Full AISG operation and RET antenna support, AISG2.0 compatible
  • Small and light for minimum visual impact
