What about gain antennas such as the common 1/2 or 5/8 wave?


Assuming this is a mobile install.....

A 1/2w antenna is not a "gain" antenna and requires a high-impedance
feed. A 5/8w also requires some impedance matching at the base, but
its benefits in a mobile installation aren't realized because of the
heavy loading required (a 5/8w at 11m is about 22 feet high!).


I would venture to say gain antennas would be much better
performers for the other 99.999% of us.


I wouldn't "venture to say" anything of the sort. I have installed
lots of antennas and tuned them up with a FSM. So far I haven't found
a single antenna that can beat a properly installed (and sometimes
improperly installed) 1/4w (102") whip.
