IDLE-QUDS47-ESSEN-OPP

Specifically designed to address the demand of the global DTH market for a competitive and 4G/LTE protected solution, this LNB provides optimized reception capabilities using the latest technology in satellite reception. It enables the reception of satellite TV from a single satellite and its distribution to four Set-top boxes or to two dual tuner PVR. The LNB supports Standard, High Definition and the latest Ultra HD (4K) transmissions, delivers excellent RF performances, very low power consumption and importantly engineered to mitigate interferences from 4G/LTE transmissions. Manufactured to the highest industry quality standards and engineered to meet strict specifications, this LNB is an ideal solution for DTH operators and satellite broadcast reception across the world.

 

Main Features:

• Low Phase Noise, DVB-S2 (HDTV/UHD) compliant

• Low Noise Figure

• High Cross Polarization Isolation

• High Frequency Stability (PLL-based)

• Low Power Consumption

• Greater immunity against 4G interference

Frequently Asked Questions

What is a feedhorn?

The feedhorn is the part of a satellite dish system which gathers the reflected signal from the dish and focuses it towards the LNB.

What is an LNB?

An LNB - Low Noise Block (also called an LNC- Low Noise Converter), is used for communications (broadcast) satellite reception. The LNB is usually affixed either in or on the satellite dish.

What is an LNBF?

An LNBF is an LNB with an integrated feedhorn

What is a Monoblock LNB?

This design consists of two independent LNBs in a single case. The two LNBs can be automatically addressed with any DiSEqC 1.0 or higher receiver. In some cases they can also be addressed with ToneBurst / MiniDiSEqC. However, they are only available for satellites with a fixed 3 degree, 4.3 degree, 6 degree …spacing. In Europe, for example, there are monoblock single, twin and quad LNBs for the Ku band, which have a pre-defined spacing of 6 degrees (for Astra 1 / Hotbird , for example).

Why can I receive only one satellite with my Monoblock?

Monoblock LNBs are designed for a specific dish size, 80cm for example. If your dish is too small (70cm for example) or too wide (90cm for example) it is not possible to receive both satellites together. Please choose the dish size for which the monoblock LNB has been designed.
