Antenna Diversity
This allows the PC3000 to use the stronger signal from the two antenna ports.
Diversity can help the radio maintain the RF connection in areas of
interference. Due to the nature of how RF signals are affected by the surroundings, one
antenna may be in a RF ‘null’ where the signal is very weak, but the other antenna (even though it is only
a small distance away) might not be. Therefore, the PC3000 would automatically
select the antenna that has the highest signal strength. This is the
recommended setting for the standard snap on antenna.
