I have couple ambiguities regarding outdoor mesh solutions,
(1) As per the compare page 1510 can only operate in Lightweight mode but there is nothing mentioned about the 1520 behavior, can we operate 1520 in Autonomous mode without using any controller?

(2) i have a situation where i need a single p-to-p link to the root bridge but i have six antenna ports available on 1520 so can i use a single 28 dBi dish antennae in 5 Ghz and 5 antennae for 2.4 ghz indoor coverage?
(3) are there any other models available for dual band outdoor connectivity other than 1500 series?
