I?m getting ready to install our GDL-82 and trying to figure out the best location for the actual GDL-82 box. Our behind the panel space is pretty much occupied and an installation there requires coiling the required six feet of coax so, I was wondering if anyone has mounted the box under the seat pan and near the transponder antennae? Seems like it would make sense as you could perhaps use the original coax to connect to the box and the run to the GPS antennae would utilize most, if not all, of the required six feet of coax. This would also minimize the time spent on my back, upside down, while trying to decide if I need EMS to get me out of there! I have to say that I didn?t build the plane and I haven?t pulled the pan out yet. Is there something there that presents a problems this type of install?
