regular radio antenna

The truck i am in right now has no antenna on the right side. I believe it is the music radio antenna. I do have an antenna on the left side which i think is for the cb. I was going to replace the left side one for a better cb antenna. Should i just put the one i am taking off the left side onto the right side? or is there a really good antenna i can get at one of the truck stops?

 

does that matter? they all have antennas this is not a question about a truck it is about what is a good antenna for the radio. I drive an older international 9400i.

 

okay thanks. so i will just get a nicer antenna for the cb and use the one i have for the radio. The person who had the truck before me took the antennas with him to his new truck. so the shop had one laying around and put it on the driver side. the passenger side is wired and mounted it just has no antenna screwed into the hole. Thanks for your help. any recommendations on cb antenna? I just have a cobra 29 cb so nothing fancy.
