DTV DTX-30 Satellite Diplexer - Combine/Separate TV & Satellite Signals

Run your TV aerial and satellite signal down a single cable. The DTV DTX-30 is a diplexer that combines a terrestrial TV signal and a satellite signal onto one cable for transmission, then separates them back into two distinct signals at the other end — useful wherever running two separate cables isn't practical.

This makes it a handy tool for installations where only a single cable route exists between a dish or aerial and the viewing point, such as older homes, apartments or outbuildings with limited cable access. Combining both signals onto one line avoids the cost and disruption of installing additional cabling.

Key features

• Combines TV and satellite signals onto a single cable
• Separates the combined signal back into two outputs at the far end
• F-type connectors for secure, standard cable connections
• Compact, simple in-line design
• No power supply required for basic operation

Ideal for

• Homes with only one existing cable run to a dish or aerial
• Apartments and outbuildings with limited cabling access
• Installers avoiding the cost of running additional cable
• Simple single-cable TV and satellite distribution setups

Good to know

A matching diplexer is generally needed at both ends of the run — one to combine the signals before the cable and one to separate them again afterwards — so check your installation requires this configuration before purchasing. Use quality F-type connections to minimise signal loss along the cable run.
