Are there any websites or information available to explain more detailed
about using antenna tuners for 2m ? I use two, one for 2m and one for
156megs frequently.

The antenna tuner does bring the reflected power down to almost 0 to the
radio and improves communications both receive and transmit. Could there be
a hidden damage or danger?

No damage or danger. But why not just fix the antenna? Making the antenna
present a proper load in the first place will give you much better results
than trying to fudge around a bad antenna with a tuner.

No it doesn't. It only brings the reading on the meter down to almost 0.
Do you really believe it?
