It seems most Mazda have broken antennas and that just didn’t work for me or my mini. If you have every replaced an antenna, you know they attach from the under side of the fender. My plan was to unbolt the side of the fender and try to pull it out enough to get to the antenna. This actually worked, but I noticed there were only two bolts left holding it on.
Might as well take it all the way off since its still kinda in the way.
