I got mine today(2nd one), but no tuning instructions. I'd like to skew the frequencys down just a hair. No real way to make the antenna longer, just shorter. So I assume this antenna is not made to be tuned?
Try using it the way it is. It will probably work fine at your desired frequencies. They are not that far off the spec. frequencies.From the factory it says 150-165, 450-470, and 806-940. I would have liked to change it to 145-160, 445-465, ect. . . I can live without it changed.
