Review on 🚗 Enhanced RoadPro RP-550 36" Adjustable Ring CB Antenna with Advanced Tunability by Pressure Cook

This "antenna" is not worth your time or money. Nearly impossible to set up after having to fix a broken connection. As for the adjustment rings, I'm not entirely sure, they didn't seem to do anything when adjusting their position. Most of the case is made of cheap plastic and doesn't feel very solid. I won't return, it's easier to throw it away.
