Failed to load module: no module named antenna

I am a beginner with MAVProxy.

I am successfully able to execute: --console --map
Arm the quad, takeoff, etc.

Have moved into the modules and can use the default modules such as adsb.

Am able to import the joystick module.

When I try to import the antenna module I am unable, can anyone provide any insight as to why? Or where I would find more information?
