"Aux" connector on airport card?
The one on the left is labelel "main" and is, presumably, where one attaches the cable to the airport antenna.
What is the "aux" post for? One site I stumbled on suggested it was for an auxiliary antenna that would be used when the primary can't find a strong enough signal. But the A1176 doesn't come with an auxiliary airport antenna (does it?).
When I purchased my used A1176 the airport antenna and cable were missing; now that I've bought a replacement I also have a spare bluetooth antenna and cable. Would it hurt or help to use my spare as an auxiliary, perhaps taping it where the latest Minis seem to have yet another antenna?
