I need to replace the antenna on a Uniden Mystic VHF radio so if anyone has a broken Mystic with an intact antenna I would love to hear from you. Please PM me if to discuss a price if you have one.
Have you had any success yet ? If not you could try broadening your search into Radio forums such as Junksale. Uniden gear gets used by radio amateurs and listeners. (Obviously you need to ensure any antenna offered to you is resonant on the Marine band)
