TMA Tower Amplifier

The tower amplifier is mounted on the sector antenna. This provides extra RF gain and
additional flexibility in location for mounting the sector antennas. The transmit/receive
operations are synchronized using the TMA synchronization signal.

RF In Ports

The RF-1 and RF-2 input ports (TNC type F connectors) conduct RF signals between
the Ellipse TMA and the TMA RF Tower Amplifier system.

TMA-SYNC Port

The TMA-Sync port (TNC / F connector) is used to synchronize operation of the remote
TMA SYNC RF Tower Amplifier units.
The TMA-SYNC ports of all units must be interconnected using LMR-195 (or equivalent)
coaxial cable terminated with TNC / M connectors. Use TNC Tee adapters to connect
units in a daisy-chain configuration.
Important: Multiple RF Amplifier units can be synchronized using up to 46 m (~150 ft).of
interconnecting synchronization cable.
