Though i have not tried with airtel but with DD FD (Solid FTA STB) i have tried and it doesn't work. Super LNB is a Unicable II LNB while normal STBs supports Universal frequency ranges.
So you need special hardware/software to make it work.
Both LNB provides better signal quality for Ku Band signals while Super LNB can handle multiple connections with one dish (and even 1 port can be splitted into multiple using splitter).
