LNB TechniSat UNYSAT 11,7–12,75 GHz, conector F, feedhorn Ø4 cm, 140 mA, cinzento

TechniSat UNYSAT LNB receives Ku-band satellite signals in the 11.7–12.75 GHz range and downconverts them to L-band for delivery to satellite receivers. Housed in a compact grey enclosure with a feedhorn diameter of 4 cm and an F-type RF connector, this LNB is designed for direct installation on compatible dishes and replacement of similar manufacturer-specific feeds. It supports continuous operation with a typical current draw of 140 mA and weighs 0.366 kg, making it suitable for standard home and small-site satellite TV installations.

Advantages

The TechniSat UNYSAT LNB offers low-noise reception and a design compatible with manufacturer-specific dish feeds, helping to preserve signal integrity between the dish and receiver. Its construction provides stable downconversion of Ku-band signals to L-band, while the compact feedhorn and F-type connector allow straightforward installation and replacement. The modest power consumption supports common receiver-supplied powering through coaxial cable.

Suitable for

• Home satellite TV systems requiring a single LNB with reliable Ku-band reception
• Replacement of manufacturer-specific feed LNBs on compatible dishes
• Small apartments and locations where compact, low-power LNBs are preferred
• Setups using F-type RF connectors and standard coaxial cabling

Key specifications

• Frequency range: 11.7–12.75 GHz (Ku-band receive)
• Feedhorn diameter: 4 cm
• Connector type: F-type RF connector
• Power consumption: 140 mA (typical, powered via coaxial cable)
• Weight: 0.366 kg
• Colour: Grey

How to use

Install the LNB into the dish feed arm or manufacturer-specific feed holder according to the dish maker's instructions, ensuring the 4 cm feedhorn seats correctly and the F-type connector is secured. Connect coaxial cable(s) from the LNB to the satellite receiver(s) or tuner(s) using properly fitted F-type connectors. The LNB is powered via the receiver through the coax; confirm that the receiver provides appropriate voltage. After connection, align the dish toward the target satellite and verify signal strength and quality on the receiver. Make fine adjustments to dish pointing and LNB positioning until satisfactory reception and channel lock are achieved.

Recommendations

Use low-loss coaxial cable for longer runs and weatherproof all outdoor connector joints to preserve signal quality. When replacing an existing LNB, confirm mechanical compatibility with the dish's manufacturer-specific feed interface to avoid fit or alignment issues. If reception problems persist, inspect cabling and connectors, check receiver power supply to the LNB, and perform dish re-alignment or use a signal meter for precise tuning.
