I am recaulking and want to remove the antenna to put new putty on. I removed the screws and it won't lift off. I am new to all this including the camper and am on my own. What else do I need to disconnect to remove it?

If you are talking about the TV antenna. you have to remove the inside crank handle spring and sealing flange. From the out side you have to remove the retainer screws, then use a putty knife to brake the seal of the sealant then lift the unit off.
