Drag and drop the Antenna selector to your HamSphere 4.0 Transceiver and you will enable the transceiver to choose from a variety of antennas. (A must for all Beams and Yagi's ect.)
At the bottum of the selector you will see three colored boxes which will show you all the available antennas:
F: A list of antennas you have purchased for the frequency you are on.
A: A filtered list of available antennas that are tuned for the frequency you are on.
P: The current antenna you are using is written on the bottom line..
