Duplexers & Preselectors

We are proud to be an authorized dealer and reseller for Fiplex products, including duplexers, pre-selectors and trunking combiners. Fiplex products are unmatched in quality and performance, with very low insertion loss, extremely high rejection and superior temperature compensation.

Fiplex is the OEM choice for radio manufacturers including Icom America and Vertex Standard. Yes, you can pay less for a duplexer elsewhere, but, the Fiplex mechanical and electrical design is unrivaled, and a Fiplex duplexer will never drift off frequency.

Fiplex products are unconditionally warranted by Red Dog Radios to meet or exceed our specifications when designing a custom system configuration for you.
