## Long description

The Triax low noise block downconverter 10.7 - 12.75 GHz Grey White is a compact LNB designed for receiving Ku-band satellite signals. It operates across the 10.7–12.75 GHz frequency range and provides an F-type RF connector for simple connection to coaxial satellite cables. With a 4 cm feedhorn diameter and a compact housing measuring 112 mm wide and 61 mm deep, this downconverter is intended for standard satellite reception installations where size and reliable signal conversion are important.
Advantages
This low noise block downconverter offers stable performance across the Ku-band frequency range with low power consumption of 240 mA. The compact form factor and modest feedhorn diameter make it suitable for use with small to medium satellite dishes. The F-type connector ensures broad compatibility with common satellite coaxial cabling, while the neutral grey-white housing supports unobtrusive installation on a variety of dish types.
Suitable for
 Residential Ku-band satellite TV reception
 Small and medium dish installations
 Replacement or upgrade of existing LNB units
 Single-cable satellite links with F-type connector
Key specifications
 Frequency range: 10.7–12.75 GHz
 Connector type: F (female)
 Power consumption: 240 mA
 Feedhorn diameter: 4 cm
 Dimensions (W × D): 112 mm × 61 mm
 Housing color: grey and white
How to use
Install the downconverter onto the dish feed arm according to the dish manufacturer’s alignment instructions, ensuring the feedhorn is centered in front of the dish focal point. Connect the F-type cable from the downconverter to the satellite receiver or multiswitch. Power is supplied via the coaxial cable from the receiver; verify that the receiver provides sufficient current (around 240 mA). After mechanical installation and cable connection, perform dish alignment and signal strength optimization using the receiver’s signal meter or a separate satellite finder.
Usage recommendations
For reliable long-term operation, mount the unit in a sheltered position to minimize direct exposure to heavy precipitation and consider using weatherproofing at the F-connector. Ensure mechanical fastenings are secure and re-check alignment after strong winds. When replacing an existing LNB, confirm compatibility of dish focal length and connector type before installation.
