02 Montero Antenna

I think my power antenna gears are stripped. The antenna is stuck in the up position and the motor makes a grinding noise when the power turns on. Any fixes? Where would I find a replacement antenna? Would rather a non-powered antenna so I don't go through this again.
Thanks.

your local dealer might be able to make a fix for it.

ours was able to when the gear that moves the central locking got stripped and kept trying to open and close the locks when you open it.
