You'll need to get the apex up 50 feet or more for the pattern to  
become effective.

Ditto here. Or you might consider delta-loops. If you have high  
enough supports, these can be easy to tune and very effective.

Radials again.

I've decided that for most effective antennas, you're either looking  
for higher supports or putting miles of wire on the ground....
