Proception Terrestrial Satellite Masthead Diplexer F-Type Screened

  • High-isolation frequency-selective units for combining or splitting signals in the various terrestrial and satellite IF bands.
  • Very high isolation from SAT ports at UHF avoids excessive signal degradation due to LNB noise.
  • Fully-screened RF modules in robust diecast enclosures. Strong cast-in 'F' connectors.
  • Power pass (20V and 400mA max.) to the higher or highest frequency port.
  • Two NEW products add Band III coverage for DAB or TV to this range for the first time.
  • With equipotential bonding point.
  • Suitable for indoor or outdoor use.
  • PROCOM21TS Diplexer combines or splits all terrestrial bands (5 - 854MHz) and SAT IF.

Terrestrial Satellite Masthead Diplexer is a device used in satellite TV installations to combine the signals from a satellite dish and a terrestrial antenna onto a single coaxial cable. It is commonly 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.
