TMA2147 | MI-161

TWIN TMA 700

Designed to be deployed with 700MHz systems, this Tower Mounted Amplifier enhances cell uplink coverage 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. The MI-161 and the TMA2147 are the same product but to ease the transition for our customers both Kaelus and Microdata part numbers will be maintained.

MI-161: part number under Microdata brand
TMA2147: part number under Kaelus brand
