CB Antenna Help

My son gave me his old CB set up last Christmas and I have not had the opportunity to set it up and use it yet. Since I will be moving across country I guess now is as good as time as any. I assume that I will be able to hook it up in the rental truck so I need some antenna recommendations. Since I will eventually hook it up in my car I will need either a magnet type antenna or one that hooks on the lip of the trunk. These are pictures of what I have. Also, when you recommend an antenna will I need to get it calibrated or whatever you call it?

 

I thought since I was not a trucker I had to stay in this area. Am I allowed to post somewhere else?

 

I just thought I had to keep any questions in this area as I am not a trucker. I did ask in the CB area and it was OK. I didn't know that before. Thanks to everyone.
