| High Light | 10.7~12.75GHz Monoblock LNBF ，Dual Satellite Ku-Band LNB ，0.7dB Noise Figure Dual Satellite LNB | ||
MONOBLOCK Ku-Band LNBF designed for professional satellite reception with dual satellite capability.
A Monoblock LNBF is a single satellite dish feedhorn unit that houses two built-in LNBs (Low-Noise Block Downconverters) at a fixed, precise distance apart. This allows it to receive signals from two different geostationary satellites simultaneously using a single dish, without a motor.
Think of it as a pair of ears on a single head, each permanently angled to hear a different person talking.

This design features two independent LNBs in a single housing, allowing reception from two different satellites at slightly different orbital positions using a single dish. Switching between satellites is achieved via DiSEqC signals. Monoblock LNBs are available mostly for satellites with fixed 2°/3°/4.3° or 6° spacing, covering Ku band with single, twin, and quad outputs.
Two LNBs in One Housing: The "block" in Monoblock refers to the single, integrated unit. The two LNBs are not adjustable; their spacing is factory-set for a specific satellite orbital separation (e.g., 4.3°E/5°E, 13°E/16°E, or the very popular Astra 19.2°E & Hotbird 13.0°E, which are 6.2° apart).
Fixed Angle (Skew): The unit is designed to be mounted centrally on the dish's arm. The skew (rotation) of the entire block is adjusted during installation to match the polarization angle for both satellites.
Dish Size Requirement: Because the dish's focal point is optimally aligned for the primary (central) satellite, the secondary satellite is slightly "off-focus." Therefore, a larger-than-minimum dish size (often 80cm or larger in Europe) is usually recommended to gather enough signal for both satellites.
Connection: A Monoblock LNBF has two output cables (one for each satellite). These connect directly to a satellite receiver with two independent tuners (a Twin Tuner receiver) or to a multi-switch to feed multiple receivers.
European Free-to-Air (FTA): The classic combo is Astra 19.2°E (German, French, international channels) and Hotbird 13.0°E (Italian, Middle Eastern, Eastern European channels). A 6° Monoblock is standard for this.
International Content: Popular in expatriate communities to receive channels from two nearby satellites from their home country.
Simultaneous Recording/Watching: Allows one tuner to record from a channel on Satellite A while watching a channel on Satellite B.
