So, lets see what Saturn can do in 11th house without any conjunction or aspect from any other planet. 1st lets see what these 2 things represent --

Saturn is all that which we don't like in our life. Saturn is delay, frustration, restriction, limitation and anxiety. It is hard-work and labor. It is people of authority, like boss at your work place or father-figure at home. Saturn is Master and Servant both (depends on who uses Saturn in what way). Saturn is our Karmic debt from life. Saturn is the things we didn't treat too well in our past life. Saturn is our challenges and lessons of life. Saturn is old-age, teeth in human body, diseases, transformation etc. Saturn is discipline, organisation, structure, government, law & order etc.

11th house represents Elder Siblings, Large Organizations, Huge Structures, Higher Goals and Purposes for the Universe, Network Circle, Entrepreneurship, Friends, Gains, Income and Earnings etc.

11th house is original house of Aquarius Sign, which is Saturn's Mool-Trikona sign, so in this house Saturn feels little comfortable and relieves its negative side to a little extent and gives positive results. It is not that Saturn has become totally benefic but here it will give you results in 8 years as compared to 10 years in other houses. Delay and Hard-Work would still be there but it is just that delay won't be long. Saturn in 11th house gives good gains from network circles and large organisation but as usual after working too hard. This person will also gain from elder siblings. Their friend circle or network circle will include majority of people who are old and matured. They can also gain from speculative businesses and entrepreneurship. But again, all these gains will require the hard work and perseverance. Nothing comes with Saturn without hard work.
