Rapid Deployment

Tower Top Amplier

429-83H-01-RD Series

Designed to enhance the operation of the temporary base station, the Rapid Deployment TTA will

increase the receive sensitivity, often in excess of 10 dB, and can make up for the imbalance between

mobile and handheld users. Often in emergency situations, any increase in “talk back” range can

make the difference in mission critical communications.

The TTA system consists of two components: the Tower-Top Amplifier mounted close to the antenna

and a Receiver Multicoupler base unit. The lightweight and rugged TTA is designed to reduce wind

loading on mobile communications tower systems. In addition, the rapidly deployable package

ensures quick and reliable communications in emergency situations. To reduce the size of the TTA

and simultaneously provide 120 dB of isolation of a TX carrier, filtering has been split between the

TTA and Receive Multicoupler base unit.
