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
  • Combilent’s TMA/TTA products offer the most and lightweight and compact form factor on the market for ease of installation and integration.
  • Quality manufactured, integrated one-block unit, ensuring less points of failure and lower noise figure from less cables, components and connectors.
  • Integrated filter (band pass or duplexer) and LNA with onboard surge protection.
  • System gain setting, visual indicators and relay alarm output at the Receive Multi-Coupler (RMC).
  • Rx distribution from the RMC (AC mains or DC power supplied).
  • Combilent TMAs are 50% more compact than industry-standard TMAs.

RMC

Combilent’s Receive Multi-Coupler systems facilitate coupling of multiple receivers to a single antenna – this eliminates the need for dedicated antennas for each receiver. All RMC systems are highly integrated, and include the receive filter, LNA, distribution to multiple receivers, TMA power supply and control unit.
