little more advanced...yes. Just put the 2 LNB's right next to each other. You may need a spacer (1/2" piece of wood works good) and a hoseclamp but yes it can be done. I did it for a while and I know others have too
edit: found a pic of that particular setup (courtesy of iafirebuff)
(the 129 LNB is on the right...when dealing with multiple LNB"s they go opposite of the clarke belt)

There are also at least two different style brackets with LNB holders that you can buy to have multiple LNBs on one dish. As well, if you have a spare LNB holder, you make your own bracket out of a piece of light-weight metal and use spacers to adjust the position of the LNB.
I have found it easy to attach additional LNBs with U-bolts. You can also adjust the spacing on the 2nd LNB with the spacing of holes on the metal strip holding the two LNBs together. (See atttached)
