The antenna is bent and wont retract all the way down what do i need to do?

If the antenna is bent and won't retract fully, first, carefully try to straighten it by hand, being cautious not to apply too much force that could cause further damage. If it doesn't retract after straightening, check for any obstructions or debris in the mechanism. If the problem persists, consider consulting a professional for repair or replacement, as forcing it could lead to more significant issues.
