429-83H-01-RD, 792-824 MHz, Rapid Deployment Tower Top Amplifier System
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.

Ideal For: Temporary Basestations, Transportable Command Centers and Rapid Deployment Stations

Spec. Legend
[TTA] = Tower Top Amplifier
[MCU] = Multicoupler Unit

Optional Filters
  • Rack-mounted narrow band filters to further limit the multicoupler bandwidth. Optional filters are available to provide a narrower window ahead of the receiver multicoupler in order to achieve better selectivity for the system. (See "Compatible Devices" under the specifications table for filter selection)
  • Please specify sub-band frequency when ordering
