A nice extendable scanner or ham radio antenna. Four sections, this antenna will extend to make about a 20" long antenna. Short length is about 6-1/2". Has a Male BNC connector for those radios or scanner having a BNC Female connector. The antenna will tilt (swivel) on the mount and has a screw that can be tightened should it become loose. Usable with both digital and analog scanners. Not all scanners or radios will have a BNC connector, please ask us if you don't know what yours has. Enjoy!
