Kingtone Tetra Repeater 380-400MHz BDA Radio Communication System Coverage Solutions
-
TETRA (Terrestrial Trunked Radio) repeater designed to support public-safety networks and professional mobile-radio systems for high-security applications, such as metro underground networks, or the oil and gas industries.Bi-Directional Amplifier (BDA)can selectively amplify the signals, ensuring the frequency purity of repeated signals and the stability of output power. It has excellent compatibility and is now widely used in trunking communication systems such as TETRA, iDEN.
Kingtone offers a wide range of tetra radio solutions and repeater system to meet the needs of Professional Mobile Radio user organizations.Bi Directional Amplifier UHF Motorola Tetra System extend 380MHz 420MHz 450MHz Signal in Basement, Tunnel, High-Building
