FIPLEX RSA2-B2J 400–520 MHZ DIRECTIONAL COUPLER T268390

The Fiplex RSA2-B2J in the 400–520 MHz configuration is a specialized UHF Directional Coupler. Unlike the wideband versions, this specific unit is tuned for the UHF Public Safety and Business bands, making it a mission-critical part for police, fire, and emergency service radio systems (LMR/P25). The "B2J" suffix typically indicates a 20 dB coupling value. In a UHF DAS (Distributed Antenna System), this is used to pull a small amount of signal off the main line to feed a local antenna or monitoring equipment without significantly weakening the primary signal path
