350-520MHz coupler UHF Intercom Networking Frequency Band N-F Connector Power 200W (5-40dB)

UHF 350-520MHz Directional Coupler with N-female Connector is a kind of RF passive device for isolating, separating and combining signals, accepts an input RF signal and divides it into 2 output signals.

UHF passive directional couplers using for couples (dividing) some amount of RF signals from a transmission line with a specific coupling factor. Couplers constructs from two coupled transmission lines.

Directional couplers designed for use in Distributive Antenna Systems (DAS) for the construction of chain UHF antenna systems for subways, tunnels, high rises buildings, underground garages, etc.
UHF Directional Coupler covers wide frequency band from 400-470MHz,which has different coupling like 5dB,6dB,7dB,10dB,15dB,20dB,30dB,40dB

The image displays various components typically used in a Distributed Antenna System (DAS) or In-Building Solution (IBS) for telecommunications. These components manage and distribute radio frequency (RF) signals within buildings and other areas. 
Hybrid Coupler: An RF component used to split or combine signals, providing high isolation between ports. 
Power Splitter/Combiner: Devices that split a signal into multiple paths or combine multiple signals into one, often used in balanced circuits. 
Loads (Dummy Loads): Terminate a port with a specific impedance (typically 50 ohms) to absorb power and prevent signal reflections. 
Attenuator: Reduces the power level of an RF signal. 
Antennas (Omni and Panel): Radiate or receive the RF signals, with omni-directional antennas providing 360-degree coverage and panel antennas offering directional coverage.
