Nizkošumni blok pretvornik Preisner SPU44EN

The Preisner SPU44EN Low Noise Block downconverter by Televes is designed for satellite reception in the 10.7–11.7 GHz frequency range. With a compact 4 cm feedhorn and low power draw, this LNB converts incoming microwave signals to lower intermediate frequencies for further processing by satellite receivers. The unit's grey housing and standard connector interface make it compatible with typical home and small-scale installations where reliable signal conversion and low internal noise are required.

Advantages

The Preisner SPU44EN offers consistent low-noise performance across its specified band, supporting clearer reception and reduced signal degradation. Its modest power consumption of 150 mA helps minimize load on multiswitches and power supplies. The 4 cm feedhorn provides focused signal capture while maintaining a compact form factor that fits common dish arms and holders. The grey finish provides a neutral appearance suitable for residential installations.

Suitable for

• Single-dish residential satellite reception
• Small apartment or domestic installations with limited space
• Replacement of standard LNBs operating in the 10.7–11.7 GHz band
• Integration with satellite receivers and set-top boxes requiring low-noise conversion

Key specifications

• Operating frequency range: 10.7–11.7 GHz
• Feedhorn diameter: 4 cm
• Power consumption: 150 mA
• Color: grey
• Form factor: single-output LNB compatible with standard F-type connections

How to use

Mount the LNB at the focal point of a compatible satellite dish using the dish's LNB holder, ensuring the feedhorn is centered and aligned toward the satellite. Connect the F-type output to the satellite receiver or cabling system, and provide DC power through the coaxial cable from the receiver or an appropriate power inserter. Adjust dish elevation and azimuth while monitoring signal strength on the receiver until optimal reception is achieved. Ensure connectors are tightened and weatherproofed for outdoor installation.

Recommendations

For stable long-term performance, verify mechanical alignment after strong winds or storms, use weatherproof sealing at connector joints, and avoid routing coaxial cable near high-power electrical equipment to reduce interference. When used with multiswitches or long cable runs, confirm that the available power budget meets the LNB's 150 mA requirement.
