LNB Megasat Quattro Diavolo Low Noise Block 10.7-12.75 GHz

The Megasat Quattro Diavolo Low Noise Block 10.7-12.75 GHz is a quad-output LNB designed for fixed satellite reception systems. It converts incoming satellite signals in the 10.7–12.75 GHz band to lower frequencies suitable for distribution to multiswitches and receivers. The unit has a compact feedhorn with a diameter of 4 cm, a robust housing in black and red, and a single F-type RF connector for each output to ensure stable electrical connection and straightforward installation into standard satellite dish arms.

Advantages

The LNB provides low-noise signal conversion across the full Ku-band receive range (10.7–12.75 GHz) for consistent reception quality. Its quattro configuration supplies separate outputs for vertical low, vertical high, horizontal low and horizontal high polarizations, which simplifies connection to multiswitches in multi-dwelling or multi-receiver installations. The compact dimensions (99 mm wide, 54 mm deep) and 4 cm feedhorn diameter make it compatible with most standard reflector foci while the F-type connector supports reliable and commonly used cabling and fittings.

How to use

Mount the Megasat Quattro Diavolo LNB in the focal point of a properly aligned satellite dish using the dish manufacturer’s bracket and secure the unit mechanically to prevent movement. Connect each of the four F-type outputs to the corresponding inputs of a multiswitch or to distribution cabling labeled for vertical low, vertical high, horizontal low and horizontal high bands. Ensure coaxial cables and connectors are in good condition and torque connectors to recommended specifications to maintain signal integrity. After physical installation, verify dish alignment and signal quality with a satellite meter or receiver diagnostics and adjust the dish for maximum signal strength.

Recommendations

Use low-loss, well-shielded coaxial cable and properly crimped or compressed F-type connectors to reduce attenuation and potential interference. When installing in exposed locations, apply weatherproofing on cable connections and follow local grounding and lightning protection standards to protect equipment and maintain long-term signal reliability.
