Description
The HDTV Distribution Amplifier Distributing one antenna's signal to multiple TVs and long coaxial cables (50 ft. or more) between your antenna and your TV will result in a certain amount of signal loss. Distribution amplifiers counter this loss by increasing the overall signal strength so the coaxial cable coming from the antenna provides consistent TV reception throughout your installation. Made using professional grade, high-performance materials, the CDA 8-Output Distribution Amplifier can be used in both home and business installations where as many as eight TVs need reception from one antenna.
- Eight Output Ports–Split your antenna's signal to 8 TVs. Boost signal strength for TV reception throughout the home.
- Compatible with HDTV, CATV, analog, and digital distribution applications.
- Precision machine-sealed housing provides protection against dust ingress and water splashes.
- Excellent surge protection on all ports.
- Zinc die cast housing provides shielding from electrostatic discharge.
- Compact size for indoor use. Can be used outdoors under an eave.
- Supports ATSC 3.0, NextGen TV, and UHD 4K, 8K broadcast signals.

An HDTV distribution amplifier, is a device used to split a single high-definition multimedia interface (HDMI) signal from a source device, such as a cable box, Blu-ray player, or gaming console, and distribute it to multiple displays or screens simultaneously.
These devices are commonly used in home entertainment systems, conference rooms, classrooms, and other settings where multiple displays need to receive the same video and audio content from a single source. They come in various configurations, typically supporting different numbers of output ports, such as 2, 4, 8, or more.
HDTV distribution amplifiers are especially useful when you want to mirror the content from one device onto multiple screens without having to switch cables or devices. They ensure that each display receives the same high-quality video and audio signals without degradation.



FAQ
Q: Do HDTV distribution amplifiers support 4K Ultra HD signals?
A: Yes, many modern HDTV distribution amplifiers are designed to support 4K Ultra HD signals, ensuring that the highest resolution and quality are maintained across all connected devices.
Q: How do I choose the right HDTV distribution amplifier for my setup?
A: Consider the number of outputs you need, the types of connections supported, whether it supports 4K Ultra HD signals, and any additional features such as built-in equalization or amplification adjustment.
Q: Are there any special considerations for installing an HDTV distribution amplifier?
A: Make sure to use high-quality cables and connectors to minimize signal loss. Also, consider the distance between the distribution amplifier and the connected devices, as longer cable runs may require additional signal boosting or equalization.
Q: Can I cascade multiple HDTV distribution amplifiers together?
A: Yes, you can cascade multiple distribution amplifiers together to distribute the signal to an even larger number of displays or devices, but be mindful of signal degradation over multiple cascaded units.
