Item: 5104

IDLK-SINL20-KAKUO-OPP

This industry-first and unique dual band Ka/Ku LNB is designed to receive Ku (10.7 to 12.75 GHz) and Ka (21.4 to 22.0 GHz) TV, radio and data channels with linear polarity (Horizontal/Vertical) from the same orbital position at 25.5° East. It can be used with standard offset dish antennas of 60 to 90cm diameter and F/D of 0.6.

 

The LNB has two ports – one supporting either Ku or Ka and the second port fixed to deliver Ka-only. The selection between Ku and Ka band is based Tone Burst or DiSEqC 1.0 commands. The product is supplied with a 40mm ring adapter to ensure compatibility with the majority of already installed legacy dish antennas.

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.
