I have just got hold of a 43cm zone 1 minidish, and have been testing it with various old analogue receivers.
You will easily get all the transponders off 19E, although the Astra 1B channels are a bit rough.
Other experiments have shown that Hotbird is generally poor, although a couple of the stronger transponders are ok (DWTV is fine)
5W for the French stuff is fine
16E only get ESC1
30W - no problems receiving the mainly scrambled Canal+ channel
5E - can get the Astra 1 test cards ok, although quality isnt brilliant. Even get the Sirius promo channel.
42E - can only get Show TV, and the quality is awful.
Am in the middle of testing the digital channels, but I have been surprised at how strong some of the digital channels come in on some of the weaker satellites.
Full results will be posted on my website when I have the time to write them up.
