I have always been told that any metal part can cause interference if in close proximity to your antenna. I have had a lot of suceess by running a 1/2" piece of fuel tube from under the fuse. I drill a small hole and run it through, then add pieces or 1/4" tube along the bottom of the fuse. A dab or epoxy and a small staple to hold them in place. No ugly antenna wire from fuse to rudder and it looks reallllly clean. The only downside is the wire tends to be alittle long. However you take up the slack is one you, but I have never heard that it can double up on itself and mess up.
