OK, we also had scheptisism about this antenna working very well due to the small size.  We put one on Joe's car. It looked great of coarse.  He put a President Lincoln in there for the test.  Then he drove off checking in every couple minutes untill he was around S-3 level in our radio (mobile also).  Joe had gone 6 Miles (then he was home).  That's not it's max range, but maybe the max you might want to be using it at.  We feel the test was a success since we didn't expect more than 3 miles when we started.
