Wideband 40mm LNB with Horizontal/Vertical ports


Item: 5277


Specifically designed to meet the increasing demand of DTH operators for lower cost MDU and Multi-tuner Home Gateway installations, this professional LNB is based on a single 10.4GHz local oscillator delivering outstanding RF performance over the entire frequency range (L-band) over two output ports (vertical and horizontal) combined with a greater immunity against terrestrial/4G inter-ferences.


Manufactured to the highest industry quality standards and designed to meet strict specifications, this LNB is an ideal solution for a cost-effective reception of one satellite and its distribution to multi-tuner home gateways or to compatible Unicable II (dCSS) wideband multiswitches.


Main Features

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

• Low Noise Figure

• Low power consumption

• High Cross Polarization Isolation

• High Frequency stability

• Greater immunity against 4G interferences

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.
