Satellite Quattro LNB fuba DEK 417 with 40 mm Feed and mobile-signal shielding (21510039)

The fuba DEK 417 Quattro LNB with 40 mm feed and mobile-signal shielding is a satellite downconverter designed for fixed multi-dwelling or single-dwelling reception systems. It provides four independent outputs corresponding to the four standard LNB bands (low/high, horizontal/vertical), enabling connection to a multiswitch or direct distribution network. The integrated shielding reduces interference from nearby mobile networks, while the 40 mm feed ensures compatibility with dishes and mounting systems that accept this standard diameter.

Advantages

The unit offers stable signal conversion across the Ku-band with four dedicated outputs for separate polarisation and band paths, simplifying multiswitch integration and larger distribution setups. Its metal housing and dedicated shielding improve immunity to mobile-signal interference and preserve signal quality in environments with strong cellular coverage. The standardized 40 mm feed facilitates mechanical compatibility and straightforward installation on compatible reflectors.

Suitable for

• Multiswitch-based satellite distribution in apartment buildings and commercial sites
• Fixed home installations requiring separate band outputs for professional distribution
• Installations in areas with strong mobile-network signals where additional shielding is needed
• Replacement of existing 40 mm LNBs in compatible satellite dishes

Key specifications

• Quattro LNB configuration: four independent outputs for low/high band and horizontal/vertical polarisation
• Feed diameter: 40 mm compatible with standard 40 mm feedhorns and mounts
• Integrated mobile-signal shielding to reduce interference from nearby cellular transmitters
• Weather-resistant housing suitable for outdoor satellite installations
• Intended frequency range: standard Ku-band satellite reception (four-band distribution)

How to use

Mount the fuba DEK 417 to a compatible satellite reflector using the 40 mm feed connection and secure the unit according to the dish manufacturer's instructions. Run coaxial cables from each of the four outputs to the inputs of a multiswitch or to separate distribution lines. Align the dish to the desired satellite using a signal meter or receiver feedback, then tighten mounting hardware to maintain stable alignment. Ensure all F-type connectors are properly tightened and weatherproofed for outdoor exposure.

Usage recommendations

For best performance, use low-loss coaxial cables and quality F-type connectors. When installing in locations with strong mobile coverage, verify grounding and additional surge protection. If integrating with a multiswitch, confirm input labelling and wiring order for low/high and horizontal/vertical outputs to match the multiswitch inputs.
