Conversor descendente de bloco de baixo ruído TechniSat 0000/8390

The TechniSat 0000/8390 Low Noise Block downconverter (LNB) is a compact satellite signal receiver accessory designed for use with parabolic satellite dishes. It features a 4 cm feedhorn diameter, an F-type RF connector for cable connection and a black housing. With low power consumption of 150 mA and a lightweight construction of 0.2 kg, the unit supports standard satellite reception and signal downconversion to a frequency suitable for consumer satellite receivers.

Advantages

The LNB's compact form factor and shallow depth (128 mm) make it suitable for installations where space behind the dish is limited. Its low current draw (150 mA) reduces load on power supplies and multiswitch systems. The 4 cm feedhorn design provides a controlled aperture for focused signal collection, while the F-type connector ensures compatibility with common satellite coaxial cables. The black colour and modest weight simplify handling during installation.

Suitable for

• Residential satellite TV reception with standard dishes
• Replacement of existing LNBs with similar physical dimensions
• Small installations where compact feedhorn size is required
• Setups using F-type coaxial connections

How to use

Mount the LNB to the dish feed arm according to the dish manufacturer's instructions, ensuring the feedhorn is centred in front of the reflector. Connect a properly terminated coaxial cable with an F-type connector between the LNB and the satellite receiver or multiswitch. Provide appropriate power from the satellite receiver or a compatible power inserter; the device draws approximately 150 mA. After installation, perform dish alignment and receiver tuning to establish an optimal satellite signal.

Recommendations

Verify mechanical fit with your dish's LNB holder before purchase. Use weatherproof F-type connectors and, if required, apply suitable sealing at the connection to protect against moisture. For multi-receiver installations check power and switching requirements of your system to ensure compatibility with the LNB's current draw.
