I don't believe in them.
If you can't resonate your antenna, then what are you doing?
If you use a tuner, you are creating a voltage divider effect that
creates a reactive load in your shack, to ground that makes your antenna
"feed line + radiating elements".
Over the years, the importance of having at least a 2:1 match with at
least 1.5:1 some where in the the antenna design.
Proper antenna design for your favorite frequencies is the best choice.
I currently use a multi-element dipole to cover 80,40,20,15 and 10 meters.
I just use a VSWR bridge and back off the power when the SWR rises close
I am not saying my answer is the best, I am only stating my opinion.
Just like microphones in the sound work I help out with at church. If
they are not singing into the mic, I cannot "fix it" without creating a
gain structure that is sucking up to feed back"
You need to fix your problems at the source.
I our cases, it is resonance of your antenna, by some means.
Even my hamstick on my jeep does great due to attention to resonance.
