## Summary description

Compact Low Noise Block downconverter (LNB) BLOW Inverto IDLT-QTL412-ULTRA-OPN for satellite reception. Features an F-type RF connector, 230 mA power consumption and a 4.9 cm feedhorn diameter. Dimensions: 142 × 79 mm (W×H). Designed to convert and amplify Ku-band satellite signals for home or small-scale installations.

## Long description

The BLOW Inverto IDLT-QTL412-ULTRA-OPN Low Noise Block (LNB) is a compact Ku-band downconverter designed for satellite reception in home or small-scale installations. It features an F-type RF connector, a 4.9 cm feedhorn diameter and a measured power consumption of 230 mA. With external dimensions of 142 × 79 mm (W×H), the unit combines a novel feed horn design and high-spec front-end components to deliver improved conversion gain, low noise figure and enhanced phase noise performance compared with standard LNBs.
Advantages
This LNB is engineered to improve reception at the edges of a satellite footprint, with better handling of long coax runs and use with smaller dish sizes. Improved cross-polarization isolation and advanced filtering reduce the impact of interfering and spurious signals. The design supports distribution via a multiswitch to multiple receivers and is suitable for receiving Ultra High Definition broadcasts where available.
Suitable for
Residential satellite reception on small to medium dishes
Installations with long coaxial cable runs
Sites near the edge of a satellite footprint or with marginal signal levels
Setups that distribute a single satellite feed to multiple receivers via a multiswitch
Key specifications
Feedhorn diameter: 4.9 cm
Connector type: F-type RF connector
Power consumption: 230 mA
Supported band: Ku-band downconversion
Dimensions (W×H): 142 × 79 mm
Enhanced front-end components and filter design for improved conversion gain and low noise figure
How to use
Mount the LNB on a compatible Ku-band feed arm or bracket so the 4.9 cm feedhorn is centered in the dish focal point. Connect the F-type RF connector to the coaxial cable running to the receiver or multiswitch and ensure the supply voltage is provided through the coax from the satellite receiver or multiswitch. Align the dish for optimal signal quality using a signal meter or receiver diagnostics and tighten all mounting hardware to secure the LNB in position.
Usage recommendations
For best performance, use a well-aligned dish sized appropriately for your reception location, high-quality low-loss coaxial cable for long runs, and a compatible multiswitch if distributing the signal to several receivers. Periodically check weather seals on the F-connector and housing to maintain signal integrity.
