I changed antenna yesterday and put a magnetic mount on the hood of the truck. No change, The swr was about the same with either antenna. On channel one the swr is very low on channel 40 it is high, channel 19 it 3.1 or so. drove down interstate 30 about 100 miles east of Dallas and never heard a word out of radio. I am calling the MFG tomorrow and talk to tech service. I have a 40 channel Cobra that does the same thing but it is old and I just figured it was bad. The weather channel on it worked well but cb was quite. That is the reason I bought the new one. The needle goes way over when I key the mike, like it is sending a signal. Thanks again for all the input
