Best Sale Reliable High Power Uhf Repeater Long Distance Public Safety Uhf Broadband Amplifier (BDA) is used for On-Site radio coverage enhancement. BDA ‘s have a few components: A donor antenna collects signal from the rooftop where it is strong and delivers it to the BDA for amplification. The amplified signal is delivered to one or more distribution antennas in areas which have poor coverage.
According to your requirement for working frequency, you can choose either type of Kingtone Repeater:
1, Band Selective RF Repeaters System: to amplify all signals in the whole band (Various bandwidth is available upon request).
2, Wireless Channel RF Repeaters System: to amplify only the signals transmitted by the customized 1 or 2 or 4 or 6 or 8 channel (A narrow band with customized central frequency)
Typical application scenarios of this BDA: tunnels, buildings, subways, and outdoor scenarios such as stadiums, rural areas and dense urban areas.
