Review on Nagoya CB 72 Coil Loaded Magnetic Connector by Patrick Cox

I have a new Uniden 980 SSB CB and bought this antenna. I installed it in the center of the roof of my 2014 F-150 pickup. The initial SWR readings were terrible and indicated the antenna was too short. I adjusted the length to make it longer but still got a dangerously high SWR (5+) on both channels 1 and 40. I added another section to the antenna and was able to get an SWR of about 1 on channel 40, Reach 5 but still 4+ . on channel 1. Since I had to add another section to the antenna, I think it is either defective or of poor quality. I wanted to give you a chance to respond before leaving a review.
