MI-183

MI-183

TMA TWIN 1800/2100 with L-Band bypass

Designed to be deployed in collocated L-Band, 1800 and 2100 systems, the Kaelus MI-183 enhances cell uplink coverage in 1800, 2100 through improved system noise figure, thereby saving operational and capital expenditure.

FEATURES

  • Improved base station sensitivity through gain in the 1800 and 2100 uplink
  • Internal diplexing on the antenna port of L-Band, 1800 and 2100 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
