I just bought a 2010 Ultra. The guy had taken both antennas off to cover the bike over the winter. When I looked at it he just picked up both antennas and screwed them both in saying they were the same. Seems odd to me to have the same antennas for radio and cb. Is this correct?

 

The antenna's are marked, the CB is on the right rear. Probably didn't care bike sold !

 

they are the same as far as i can tell. each one is labled at bottom where it screws in.
each winter i take both of mine off and never paid any attention to which one goes where. they will work fine

 

They are marked and they are different. On my bike the cb is on the left but I have a RGU

 

They are marked at the base of the antennas. cb is on the right and the radio is on the left.

If they are J and M shortys,they are interchangeable.

 

I put a dot of fingernail polish on the antenna and antenna base on one antenna the other left stock, this is on my '13 Road Glide Ultra. No confusion here and the stock ant. are different.

 

Just so you know. 2009 and later use a different (though they look the same) cb antenna than 2008 and earlier.

 

i don't believe the op was questioning which side of bike is cb or radio. i understood it to be the antenna's only.
