All the current model handheld CB radios we stock use the same type of antenna with a BNC connector. A BNC connector is the type that you push down and twist to attach. We carry 3 types of replacements for handheld antennas. The SA1 is a 9.5 inch flexible rubber antenna similar to the antenna that ships with most handheld CB's. The SA2 is a similar antenna, only longer at 2 ft. This antenna will give your handheld a little more range. The Cobra HATA antenna is a 27 inch telescoping antenna. It is not flexible like the other two.
