DPF 70/6-150 Antenna Duplexer
DPF 70/6-150 Antenna Duplexer is a professional-grade, 6-resonator duplex filter designed for use in high-performance radio base stations and repeaters. Engineered for the 138–175 MHz VHF band, this compact unit allows for the simultaneous operation of a transmitter and receiver on a single antenna with high isolation and minimal insertion loss. This duplexer is the industry standard for PMR (Private Mobile Radio), Public Safety, and Marine applications where interference-free communication is critical. Its ability to handle up to 150W makes it suitable for high-power base stations, while the six-resonator design provides the “extra” isolation needed in crowded RF environments.
