The KU-Band Monoblock Twin LNB seamlessly integrates two independent LNBs with dual-output technology, enabling you to receive signals from two different satellite positions simultaneously using just one dish, while supporting two televisions for independent viewing and free switching. Whether you want to enjoy programming from Astra 19.2°E and Hotbird 13.0°E simultaneously, or need different rooms to watch channels from different satellites, Monoblock Twin delivers with ease.

A: This design consists of two independent LNBs in a single housing and allows a user the potential of receiving the signal from two different satellites which are at slightly different orbital positions from a single dish installation. The switching between the satellites is achieved via the use of DiSEqC signals. Monoblock LNB's are available mostly for satellites with a fixed 2°/3°/4.3° or 6° spacing and the range covers Ku band Monoblock switch single, twin and quad outputs. For example where a 2° Monoblock LNB could be used is for the reception of 5°W and 7° W or with 3° distance for the reception of 13° E and 16° E.
A: Many TV channels and services are broadcast from clusters of satellites positioned close together in the sky (e.g., 6°, 4.3°, or 3° apart). Instead of installing two separate dishes or a heavy, expensive motorized dish to swing between them, a Monoblock LNBF provides a simple, fixed, and cost-effective solution.
A: If you use two dual-tuner receivers, you can theoretically record up to 4 channels simultaneously (2 per receiver), while also watching two additional channels.
A: No. Each output port of the Monoblock Twin LNB corresponds to a fixed satellite, no external DiSEqC switch required, plug and play.
A: We recommend using a dish of 80cm or larger to ensure sufficient signal margin for the offset satellite. Exact size depends on signal strength in your area.
