These LNBs are commonly retro-fitted to a minidish in order to provide up to four independent outputs. This allows connection of up to two PVR (twin tuner) devices - such as Sky Plus or the Freesat Plus receivers - or more than one standard receiver (or a mixture of both). When connecting multiple receivers (or one twin tuner PVR) to a satellite dish, the cable cannot simply be split - a twin, quad or octo LNB must be used. Since a twin output LNB for the standard Sky minidish is no longer available, a quad LNB must be used if up to 4 dish outputs are required (unused outputs can be left unused or blanked off).
Despite the claims of many retailers that there is a 'one size fits all' type of quad LNB for a standard Sky minidish, there have actually been three subtle changes in the design of the minidish over the course of several years. Although the LNB itself is the same, the specification of the arm attachment to the dish varies, resulting in three distinct types of LNB, each suitable for a particular design of dish.
We refer to these different fitting types as follows:
Type 2: Standard arm fitting
Type 1: Narrow arm fitting
Type 3: New style fitting (2009)
Identify the correct type of LNB for your dish
Type 2: The majority of dishes accept a type 2 LNB. These dishes have a dish arm that measures approximately 30mm x 20mm across the outer cross-section of the arm.
Type 1: The dish that accepts a type 1 LNB will measure approximately 25mm x 12mm on the outer cross-section of the dish arm. If you have this type of dish arm, you must buy a type 1 LNB - the type 2 or type 3 LNBs cannot be adapted to suit.
Type 1 LNBs are no longer manufactured. An additional £20.00 will be added to the standard £10.00 cost of this item, if you select this type of fitting. See options at the bottom of this page.
Type 3: A third dish type has recently been introduced. If you are fitting an LNB to a minidish supplied in 2009, you need to check whether you need a type 2 or type 3 LNB. The dish that accepts a type 3 LNB can easily be identified by shape of the dish arm - rather than a closed box section, the dish arm is a 'U' shape (measuring approximately 27mm x 20mm).
You can select your LNB type from the options at the bottom of this page.

These LNBs can be used successfully throughout the UK, France, Belgium, Netherlands and Ireland. They can only be used with the elliptical Zone 1 and Zone 2 Sky dishes. They are not intended to be used with a dish that takes a standard 40mm fitting, generally used outside the UK.
