IDLB-TWNM21-MNO43-8PP

Specifically designed for the European DTH markets, this Monoblock LNB allows for dual satellite reception. It can be used for satellite broadcast reception (on an 80cm dish antenna) of any two satellites spaced with 4.3°. It enables the signal distribution to maximum two Set Top Boxes with Single Tuner (or one STB with Twin Tuner). The LNB is optimized for High Definition transmissions and provides excellent Noise Figure performance. Designed to meet strict specifications and manufactured to the highest industry quality standards, this LNB is an ideal solution for satellite broadcast reception across Europe.

 

Main Features

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

• Low Noise Figure (0.2 dB)

• Low Power Consumption

• Very high Cross Polarization Isolation

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.
