TMA2145 | MI-176

TWIN TMA 700/800

Designed to be deployed in co-located 700 and 800MHz networks the Kaelus TMA2145F01V1-1 provides gain in the 700 and the 800 uplink bands.

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-176 and the TMA2145 are the same product but to ease the transition for our customers both Kaelus and Microdata part numbers will be maintained.

MI-176: part number under Microdata brand
TMA2145: part number under Kaelus brand
