Too bad a "Rising SD Antenne" tab button couldn't be added to the interface in the Radar section?
All in all this is a "must have mod"!
I can't count how many times this feature has saved my bacon on patrol.
Now, before surfacing I always poke my antenne up to search for enemy planes and I don't have to worry about being "jumped" during that awkward phase when I'm starting to surface and wait for my SD Radar to come on line.
