With it at 19ft what is the resonant freq?? 27mhz. If this is the case, depending on where you talk at you may have to either lengthen or shorten the antenna. And to make sure it was said, make sure you matching section is out together correctly and is correct with all measurements. There should be a tuning guide in the manual. Is there not? Is so that is pretty crappy. These antenna have to be out together correctly to work correctly! Do some research. There aren't any magic tricks to make them work. Setting the antenna up per the manual will get you in the ballpark I'm sure. Like it says, you will have to fine tune it unless you know what length to set the tip for the freq you most often talk on. This is where I would set it for being resonant. Again, no magic here. Every install is different and what might work for me or someone else may not work for you.
There are just too many variables. JMHO. Wish you best of luck and be safe!!


I'm just a CB'er, what do I know???
