My radio has an internal antenna tuner that can be activated to rapidly tune for the frequency in use.
My antenna has a disgusting SWR for the band I want to use (as measured with an AA-54 antenna analyzer). When activating the internal antenna tuner, it reports multiple occurrences of "Bad SWR" (or something like that). I don't know what the radio does with that information i.e. maybe it refuses to transmit?!? (I'd have to look that up in the manual).
Because of this "Bad SWR" report from the radio, I am fearful of burning out my radio by attempting to transmit on this problem band.
If I connected an external antenna tuner between the antenna feed and my radio, would/could the external tuner get the signal into "the ballpark" for a more tolerable SWR and then let the internal antenna tuner fine tune that ballpark SWR for a final SWR that would be acceptable to the radio? Or would it not be of any help?
