Last year I bought a used 26' Billfisher that has the radar antenna mounted to the front of the fly bridge. (It's the only thing I didn't like about the rigging). I plan to upgrade the radar to a Furuno 1724C and would like to relocate the antenna to a radar arch. What is the best way to attach a "folding arch" and can anyone recommend a supplier? The boat is located in Alamitos Bay (Long Beach). I would even consider fabricating my own if someone had a set of plans to work from. Many thanks.
