Description
CATV directional couplers are compatible with Regal directional couplers. The Model: 312 DC-xxdB series offers a variety of tap losses and provides excellent RF performance. This CATV Directional Coupler feature 5/8 inch-24 NEF-female ports for in and output cable connection on the housing. The couplers may be strand mounted through the clamp at the back of the housing or surface mounted with an optional bracket. Tested under extreme environmental conditions, the couplers are designed to operate near salt water, along busy highways and in very hot conditions.
Features
◆ 5-1000MHz full band operation.
◆ Nickel plated brass "F" connector with waterproof protection.
◆ Woven metallic gasket used to provide Hi-RFI.
◆ Full weather proof sealed and strand clamp included.

Are CATV directional couplers passive or active devices?
CATV directional couplers are passive devices, meaning they do not require external power for operation. They rely on the physical properties of the components within the coupler to split or combine signals.
How should CATV directional couplers be installed?
Directional couplers are typically installed inline with the main cable line, either indoors or outdoors, depending on the application. Follow the manufacturer's instructions for proper installation and ensure that connections are secure to minimize signal loss and interference.
Can CATV directional couplers be used for satellite TV systems?
Yes, directional couplers can be used in satellite TV distribution systems to split or combine signals. However, it's important to ensure that the coupler's frequency range and specifications match those of the satellite signals being transmitted.
What is the difference between a directional coupler and a splitter?
While both directional couplers and splitters are used to split signals, directional couplers provide better isolation between input and output ports and are designed to allow signals to flow predominantly in one direction. Splitters, on the other hand, divide the signal equally among output ports, which can result in more signal loss and less isolation.



FAQ
Q:What are the main applications of CATV directional couplers?
A: CATV directional couplers are used for signal splitting and combining in cable TV distribution systems. They are commonly employed to distribute cable TV signals to multiple TVs or devices within a building or to combine signals from various sources onto a single cable.
Q: How does a CATV directional coupler work?
A: A directional coupler splits or combines signals by allowing them to flow predominantly in one direction while minimizing signal loss in the opposite direction. This enables the signal to be divided for distribution to multiple devices or combined from different sources onto a single cable.
Q: What is a CATV directional coupler?
A: A CATV directional coupler is a device used in cable television systems to split or combine signals. It allows the main cable line's signal to be divided into multiple paths or combined from different sources while maintaining signal strength and minimizing interference.
