Minidish

The Minidish is the tradename used for the small-sized satellite dish used by Freesat and Sky. The term has entered the vocabulary in the UK and Ireland as a generic term for a satellite dish, particularly small ones.
The Minidish is an oval, mesh satellite dish capable of reflecting signals broadcast in the upper X band and. Two sizes exist:

"Zone 1" dishes are issued in southern and Northern England and parts of Scotland and were 43 cm vertically prior to 2009; newer mark 4 dishes are approximately 50 cm
"Zone 2" dishes are issued in elsewhere, which are 57 cm vertically.

The Minidish uses a non-standard connector for the LNB, consisting of a peg about in width and in height prior to the mark 4 dishes introduced in 2009, as opposed to the 40 mm collar. This enforces the use of Sky-approved equipment, but also ensures that a suitable LNB is used. Due to the shape of the dish, an LNB with an oval feedhorn is required to get full signal.
