What F11 is made of
F11 (F eleventh) is built from the notes F, A, C, Eb, G, Bb, with the interval pattern 1, 3, 5, b7, 9, 11.
Stack 1, 3, 5, b7, 9 and 11 on a root of F and you get F, A, C, Eb, G and Bb. That interval recipe is what makes the chord an eleventh chord — move the same shape to another root and the character travels with it, which is why C11 sounds like a transposed F11.

Spelling: the notes above are written the way a score would write them, not simplified to the nearest piano key. That is why this chord is spelled with E♭ rather than its enharmonic equivalent.
