Convertisseur de bloc à faible bruit Megasat 401098

Low Noise Block downconverter Megasat 401098 is a universal Quattro LNB designed for use with multiswitch systems. It operates in the 10.7–12.75 GHz frequency range, features gold-plated F-type connectors and a 4 cm feedhorn diameter. The LNB delivers a low noise figure of 0.1 dB and supports reception of HD, 3D and 4K satellite programmes while remaining resistant to extreme weather conditions.

Advantages

This Megasat Quattro LNB provides stable digital satellite reception with an extremely low noise figure (0.1 dB) for improved picture and sound quality. Gold-plated F-terminals increase signal conductivity and corrosion resistance. Its compact white housing (60 mm wide, 128 mm deep) and robust design ensure reliable operation in freezing cold or high heat. The quattro output configuration supplies the four polarisation/band feeds required by multiswitches.

How to use

Mount the Megasat 401098 LNB to the dish feed arm and align the dish to the target satellite according to standard pointing procedures. Connect each of the four gold-plated F-type outputs to the corresponding inputs on a compatible multiswitch: Horizontal High (HH), Vertical High (VH), Horizontal Low (HL) and Vertical Low (VL). Ensure all F-connections are hand-tightened and, if exposed, sealed with appropriate weatherproofing materials. Power for low-noise operation is provided through the multiswitch and connected receivers.

Recommendations

Use this Quattro LNB when a multiswitch distribution is required; verify correct cable polarity and use quality coaxial cable (e.g., 75 Ω satellite cable) for minimal signal loss. For long cable runs, consider a multiswitch or distribution amplifier to maintain signal levels.
