Use two frequency paths in a compatible dual-band radio installation with the DBD1 diplexer. It covers 3–174 and 350–512 MHz and enables simultaneous operation when used with compatible dual-band antennas and transceivers.

N-female connections and a mounting flange provide the RF interfaces and mounting arrangement. The 50-ohm unit uses a black anodized aluminum housing and handles 150 W when connected to the correct ports.
