I tried them on my 08, didn't work well for me. Went with the HD shorty's and they seemed to work better. Tranfered them to my new bike and they work well on it too......Just my 2 cents
I have them and like them well enough. Not quite as good of radio reception as with the longer stock whip. Not sure about the CB as I don't have a CB; just got the 2nd antenna for symmetry.
i have them on my '05 ultra after haveing one of mine break off while going through mount eagle. i don't think i get as good of reception with them but i do like them better since i don't have them hang up on me going into the garage on the overhead door
