Those are two examples of C band DVB. It does require a C band LNB, and I would presume a large dish, since analog C band requires a big dish. That's why they call it C band. If it used a Ku dish and LNB it would be Ku.
MEL, you would most likely need a bid dish (BUD) like 6' or larger and
a C-BAND LNB. Even though the receivers that Sadoun has are for both C ANDKU BANDS, the antenna dishes are mainly for KU-BAND that they sell. There are a few that are for C-BAND that they have. Just go to the antenna products sections on the site to get more info on that. C-band frequencies are much lower and have a longer wavelength so the regular 3ft dishes wont pick up the signals.
