I'm trying to find out if the antenna can be repaired and/or replaced on my Precedus. There are several small cracks on the surface rendering the unit unserviceable.
I just looked at a user manual for the Precedus, and it sure looks like it's a proprietary form for the antenna - unusual. I bet you can find one used for next to nothing.
Post pictures of the unit and the antenna, and let's get the Global Aviation Iterwebz working for you.
