Just did a temporary install of a Cobra 18 Ultimate with the weather channel(s). Have been able to receive messages from the Carolinas and Arizona… which is kind of strange… but haven’t been able to get anyone to respond yet. RWS meter says the antenna is tuned properly. Did manage to tune my ATS-20+ to CB channel 10 and was able to successfully get a signal on that radio from my Cobra 18.
I do highly recommend the ATS-20+ mostly because of the price. Seriously thinking about getting rid of the radio in the old Xterra so I can free up a second single DIN slot and replacing it with the ATS-20+. It is small enough to put almost anywhere… though this is not etched in granite yet. Not sure about the car radio antenna connection.
