Trav'ler installation

I'll disagree with Bill on the Dicor under the antenna. Dicor is fantastic for sealing products, but not for attaching. Keep in mind that Dicor NEVER sets. You can move Dicor around five years later when the weather gets warm. Do you want the antenna to be able to float around when the weather heats up. I understand there are screws being used, but it's the combination of the screws and the silicone that holds the antenna onto the thin fiberglass roof. Dicor would be a HUGE mistake to use under the antenna.
