Filtern
Tower Top Amplifier (TTA)
A TTA places a low-noise preselector and low-noise amplifier (LNA) at the tower top, close to the receive antenna. This location minimizes feeder loss and reduces the overall receive noise figure—delivering stronger uplink “talk-back,” wider coverage, and more reliable site access in LMR/PMR systems. High-quality filtering and strong linearity help prevent overload and intermodulation.


Sinclair advantage: Sinclair TTA systems are delivered as a matched package with the TTA and receiver multicoupler/controller together. This integrated approach optimizes end-to-end performance, simplifies integration, and ensures a balanced site design.
