Why not remove the entire length?
Go to an auto parts store and get a powered antenna - the somewhat flexible, long, skinny, rectangular type - for around $20. Take the front fairing off, unplug the current antenna and zip tie it out of the way, plug new one in, zip tie it into place, splice it into a power source like the cigarette lighter, ground it, and you're good to go! Oh yeah - reinstall the fairing before you ride off to check the reception!
