Well, I have to disagree on this statement.

Diversity does not do a lot in fixed reception. That's right, but depending 
on the TV-standard the diversity gain in mobile reception can be enormous.

Several field trials we did in the past years have shown that large parts of 
the trial route which have not worked at at all in single receiver work like 
a charm in diversity.

Maybe the route-selection in this cases was biased to show off the 
performance of diversity ... well, it worked - diversity showed off.
