  • High-Split Frequency Separation: Routes 5–204 MHz upstream signals through the LOW port and 258–1800 MHz downstream signals through the HIGH port for high-split cable broadband applications.
  • Low Signal Loss and High Isolation: Maximum insertion loss is 1.5 dB on the LOW path and 1.8 dB on the HIGH path. Isolation is at least 45 dB at 5–204 and 258–1218 MHz, and 40 dB at 1218–1800 MHz.
  • Reliable ECT Connections: SCTE-compliant Eclipse Contact Technology F-ports provide increased contact surface area for lower contact resistance and dependable connections in 75-ohm coaxial systems.
  • Durable, Sealed Housing: Die-cast zinc-alloy construction, corrosion-resistant tin plating, and a fully soldered backplate provide RFI shielding. A 15 psi pressure seal helps prevent water ingress.
  • Surge Protection and Easy Mounting: All ports withstand multiple 6 kV ring-wave surges per IEEE C62.41 Category A3. Integrated mounting tabs and a heavy-duty ground block simplify installation, with operation from −40°C to +60°C.

Antronix DPA204-258 is a 75-ohm high-split diplex filter designed to separate upstream and downstream frequency bands in cable broadband systems. Its LOW port passes 5–204 MHz upstream signals, while its HIGH port passes the extended 258–1800 MHz downstream band. Low insertion loss helps preserve signal strength, while high isolation between the bands supports reliable two-way communication.

Built for dependable service, the DPA204-258 features SCTE-compliant ECT F-ports, a corrosion-resistant tin-plated zinc-alloy housing, and a fully soldered backplate for RFI shielding. A 15 psi pressure seal helps resist water ingress, while integrated mounting tabs and a heavy-duty ground block support straightforward installation. The filter operates from −40°C to +60°C and provides 6 kV ring-wave surge withstand capability, with corrosion resistance tested to ANSI/SCTE-143 for 1,000 hours of salt-spray exposure.
