Antennae does not go up or down, motor working, can you replace the mast or do you have to replace the whole thing? How much for parts? Thank you.

Yes, you can replace the mast, but the piece of nylon cord thats broke off must be removed from the motor unit. A couple of hours of labor plus a $30.00 to $50.00 mast. So, disassembly is required. antennas are advertised every day on EBAYMOTORS for approx $20 to $150.00.
