Abstract
A keyed antenna apparatus () for adapting a wireless access point () to an external antenna () or an external antenna group (). A plurality of notches () in a keyed jack () accept a keyed plug () having thereon key projections (). The key projections () produce signals by depressing microswitches (), contacting electrical contacts (), or the like. The signals selectively cause an antenna switch () to switch a signal path () between internal antennas () and external antennas (). Further, the signals selectively cause a wireless adapter () to modify radio frequency signal characteristics, such as power.
