QUADRUPLEXER 1800/2100/2300/2600

Kaelus world proven outdoor solutions provide strong RF performance coupled with rugged features. Designed to combine 1800/2100/2300/2600 bands, this Quadruplexer saves significant capital and operational expenses by limiting feeder runs, and components needed on the tower.

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-261 and the KA-4002 are the same product but to ease the transition for our customers both Kaelus and Microdata part numbers will be maintained.

MI-261: part number under Microdata brand
KA-4002: part number under Kaelus brand
