Comet CF-416A Duplexer 1.3-170/350-540MHz, 1000W, SO-239

Simultaneous Dual-Band Operation for Amateur Radio Stations

The Comet CF-416A is a high-grade duplexer designed to allow simultaneous transmission and reception across two separate frequency bands — 1.3–170MHz and 350–540MHz — from a single antenna feed point. Combined bandpass filters suppress TVI effectively, making it a clean solution for busy shack installations. If only one port is in use, the other can remain open, though terminating with a dummy load is recommended for best results.
