hello
my understanding is that there are 3 basic configurations for the antenna,as described hereunder.I want to know the performance of each.
and give me some advice how to select the suitable configuration,if I use it in handsfree car kit.

a. external antenna (the handsfree unit contains an internal bluetooth module, the antenna is external to the unit)
b. internal antenna (all bluetooth related components are build in the handsfree unit)
c. external antenna module (all bluetooth related components are external(antenna,module)).


many thanks!

Mali
