[Nodeshot] SSH: how to retrieve antenna info?

[Fabio Capriati]

Federico, the problem is only on Bullet and Rocket devices where you can
change the antenna; but if you setup the device correctly gain parameter
you can automatically map the gain with a kind of antenna:  

10dBi -> AirmaxOmni
30dBi -> Dish 648mm
34dBi -> Dish 1050mm
from 15dBmi a 19dBmi -> Sector
