Description:

Helios Tetra800MHz  RF Repeaters system is designed to solve problems of weak mobile signal, which is much cheaper than adding a new Base Station (BTS). Main operation of RF Repeaters system is to receive low-power signal from BTS via radio frequency (RF) transmission and then transmit the amplified signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and transmitted tothe BTS via the opposite direction.

According to your requirement for working frequency, you can choose either type of Helios Tetra800MHz  RF Repeaters:

Band Selective RF Repeaters System(TM-AR-800Bx ): to amplify all signals in the whole band (Bandwidth is customized)
Wireless Channelized RF Repeaters System(TM-AR-800Cx): to amplify only the signals transmitted by the customized  2 or 4 or 6 channel (A narrow band with customized central frequency)

Features:

1. Comply with relevant regulation spectrum usage
2. Aluminum-alloy casing with IP65 protection and compact design, cool system without fan
3. ALC and AGC to ensure stable operation
4. Easy to install on wall or pole
5. Highly selective channel selector can process 1 or 2 or 4 or 6 channels simultaneously
6. Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
7. 2 RS-232 ports provide links to laptop for local test or to built-in wireless modem for communication with the NMS
8. High gain linear power amplifier technique with reliable performance

Application:

To expand signal coverage of fill signal blind area where Tetra800MHz signal is weak or unavailable.
