What do you do when the aerial gets gunked-up and won't extend fully? I've tried the obvious from a moist paper towel to using a degreasing agent but after a couple of weeks the unit starts jamming-up again. Is this just a sign that, after 7 years, it's time for a replacement - or is there a secret chemical that you can point me to?
