Glenn,

What is the swivel base mounted to, is it on the gunnel ? I'd like to see a pic of the installation if you ever get the chance. Do you have to take it apart for trailering?
The swivel base is mounted to the side of the flybridge, starboard side, screws into the cabinet in the head area with nuts inside. It is a two piece antenna. I take the top half off and store it in the cuddy, then swivel the bottom stanchion forward and velcro it to the bow rail to tow. Got an email address? I will send you pictures. Can't post pics here and MOF gone.
