Barry,
Think of your EWE as the upper half of a loop antenna... the other
half is reflected in the ground. If you raise your EWE from 10' to
12' that is really adding 4 feet to its total height. The gain of a
loop is directly proportional to its area. In the ham world, its
somewhat controversial whether a EWE really acts like half-a-loop,
but I've proved it with rather careful experimentation.... So, figure
your loop area both ways.... and that percent change in area is,
proportionally, about how much more gain you will have.

Both of my EWEs are better than 20 feet in height and moving them from
18 feet to 22-25 feet did make a difference. I wish I had the trees to
make them 50 feet in height.
