TMA TDD 3700-4100 4x4 & 8x8 mimo

Designed to be deployed with 3700-4100MHz TDD systems, the Kaelus KA-1006 enhances cell uplink coverage through improved system noise figure, thereby saving operational and capital expenditure. It can be used in 4x4 or 8x8 MIMO systems.


  • Improved base station sensitivity through gain in 3700-4100MHz
  • Suitable for 5G NR signals
  • Full AISG operation and RET antenna support
  • Small and light for minimum visual impact
