Original question was about the Harley yes. I can make the garage work just figured if I could extend it it would look nicer being hidden in the attic with just the antenna coming down.
Here is my idea: blue circle is where the battery and fuse panel are, red circle is general area where I would like to put the antenna. On bikes most of the wires are ran down the frame under the gas tank, I was hoping I could do the same with this. But if it’s going to really hurt the performance of the antenna I can try to find another place to put it.
