IDLW-TWNLRA20-D212O-OPP

This pioneering WHITE Ka LNB line was designed to enable reception of the new high bandwidth satellite TV, radio and data services in Ka band that are being launched across Europe. This Twin Ka Circular dual polarity LNB was specifically engineered to meet the reception requirements of Eutelsat for its KA-SAT satellite located on 9° East (e.g. Saorsat – Reception of free Irish TV by Satellite). The LNB features two IF outputs and supports connection to two different satellite receivers. The LNB was designed to be used with standard offset antennas of 60-90cm diameter and F/D or 0.6. The feed of this Twin LNB is designed to fit as close as 4 degrees to a allow reception from another satellite over the same dish in Europe (for example - universal Ku LNB receiving the popular Hotbird 13° East). The external diameter of the feed is about 23mm and it is supplied with 40mm ring adapter to ensure compatibility with standard dish antennas. This LNB is using the highest quality components to ensure outstanding and consistent performance and durability and is manufactured under rigorous test conditions and strict quality standards.

 

Main features:

  • Pioneering LNBF for reception of satellite services over Ka band
  • High Frequency and Gain stability
  • Low Phase Noise
  • Low Noise Figure
  • Low power consumption
  • High Cross-Pole performance

 

KA-SAT downlink coverage

KA-SAT is the first High Throughput Satellite (HTS) in Europe and marks a new generation of multi-spotbeam

high-capacity satellites. It is positioned at 9° East and covers Europe and the Mediterranean basin and has 82 tight Ka-band spot beams across Europe. Source: Eutelsat

The LNB is suitable for the reception of Saorsat - Reception of Free Irish TV and Radio by Satellite. The Saorsat service is available via Ka-Sat @ 9E, using Ka-Band (Left Circular Polarised for Ka-Band on 20.185GHz). To learn more on Saorsat service – visit http://www.saorview.ie/

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.
