TMA - TTA

Combilent provides a range of Tower Mounted Amplifiers (TMA) – known as Tower Top Amplifiers (TTA) in the USA – for use with TETRA, P25, or DMR base stations. TMAs installed at the top of the tower, close to the antenna, significantly improve coverage areas by balancing the uplinks and downlinks and eliminating cable losses.

Category Description Datasheet
TMA - TTA TMA - TTA
