The antenna I ordered for my transceiver was made for cars and trucks. The reason I bought this one was that I’d figured I could mount it on the rack at the back of the boat. So I designed a mounting plate and and thanks to a local sailor (thanks again Roger) with access to a laser cutter, it was created in no time whatsoever!

This is where the antenna sits now:

You can also see the new NavTex antenna as well.
