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.

FEATURES

  • Designed as a part band TMA with a 35MHz bandwidth, several tuning options are available. Refer to the ordering information table for details
  • Improved base station sensitivity through gain in the 700 uplink bands
  • Excellent noise figure performance
  • AISG2.0 compatible
  • Compact, low weight
