MI-188

TMA TWIN 800 L-Band+1800 Bypass

Designed to be deployed in collocated 800, 1800 and L-Band systems, the Kaelus MI-188 enhances cell uplink coverage in 800, through improved system noise figure, thereby saving operational and capital expenditure.

Microdata Telecom rebranding to Kaelus!
Microdata Telecom and Kaelus have had combined operations since Oct 2019 when Microdata acquired Kaelus. We strongly believe that by operating under one global brand we will clarify our strengthened position in the telecom market and from January 18th 2021, we are unifying the brands to Kaelus.

FEATURES

  • Improved base station sensitivity through gain in the 800 uplink
  • 2 Antenna ports: one port to low band (800) and one port to high band (1800 and L band)
  • Excellent noise figure performance
  • Full AISG operation and RET antenna support, AISG2.0 compatible
  • Small and light for minimum visual impact
  • Passive 1800 Bypass band response for feedline/antenna non-intrusive PIM testing
