    VHF UHF 136-470MHz RF Directional Coupler N Female ...
    VHF directional couplers with N-type connectors are 4-port, passive RF devices designed to sample, monitor, or split signal power within the 138–960 MHz range. These couplers, such as the Microlab CC-PS-4.8-196FN, feature low insertion loss, high directivity, and are used in Public Safety systems, antenna, and base station applications. They often use N-female connectors and handle high power (e.g., 200W+). 
    Key Features and Applications 
    • Frequency Range: Covers VHF, UHF, PS700, and PS800 bands (typically 138–960 MHz).
    • Connector Type: N-Female (N-type) for secure, low-loss connections.
    • Functionality: Used for monitoring transmitter power, coupling signals, or power distribution in DAS (Distributed Antenna Systems).
    • Performance: High directivity helps accurately measure forward vs. reflected power.
    • Power Handling: Typically designed for high power (e.g., 200W) or for low-level sampling, such as -30 dB or -40 dB. 
    Commonly Used Types 
    • Wideband Couplers: Covering VHF through 800 MHz (e.g., Tessco 85-05-0101).
    • Tapered Stripline Design: Common for achieving high isolation and minimal loss in rugged environments.
    • High-Power Couplers: Designed with N-connectors for robust, low-loss performance up to several hundred watts.
