Proception PROCOM21TS

Masthead Diplexer – Satellite & Terrestrial Signal Combiner

The Proception Masthead Diplexer is a high-performance RF device designed for satellite and terrestrial TV installations. It combines signals from a satellite dish and a terrestrial aerial onto a single coaxial cable, simplifying cabling and improving installation efficiency in residential and commercial TV distribution systems.

Engineered with high-isolation frequency-selective technology, this masthead diplexer ensures minimal signal interference between satellite IF and terrestrial UHF/VHF bands, maintaining strong and stable signal performance.

Designed for professional installation environments, the unit is fully screened and housed in a robust diecast enclosure with strong cast-in F connectors for long-term durability. It is suitable for both indoor and outdoor use.

Features

  • Combines satellite and terrestrial signals onto a single coaxial cable
  • High-isolation frequency-selective RF design
  • Supports terrestrial bands from 5–854MHz plus satellite IF

Used in situations where both satellite and terrestrial signals are needed, but only one cable can be run to a receiver.

The diplexer is installed at the masthead, which is the point where the satellite dish and terrestrial antenna cables converge. It works by separating the satellite and terrestrial signals into separate frequency bands and directing them to the appropriate output port.

The diplexer typically has three ports: a satellite input port, a terrestrial input port, and a combined output port. The satellite input port is connected to the satellite dish, the terrestrial input port is connected to the terrestrial antenna, and the combined output port is connected to the coaxial cable that runs to the receiver.

The diplexer is designed to provide minimal signal loss and distortion, and it typically has a high-quality construction to withstand harsh weather conditions.

Terrestrial Satellite Masthead Diplexer is a useful device for combining satellite and terrestrial signals onto a single cable in satellite TV installations, and it allows for the efficient use of cabling without compromising signal quality.
