If I understand your issue correctly, there is a plastic shroud at the base of the antenna that you need to turn anti-clockwise about a 1/4 turn. You can then lift the piece of plastic up to expose the connection point of the antenna. You will see where you can unscrew the base.I bought a stubby antenna recently, and want to install it in place of the original tall mast on my K1200LT. How do I non-destructively remove the original mast to screw in the stubby??? It just doesn’t seem to want to budge.
