Hi. You can turn any vertical dipole into a yagi if you put a reflector near 
it. One of the easier ones (I think) is the half-square beam (HSQ) which I have 
described at www.isy.liu.se/~mj/HAM/ANT It is quite OK to make 90 deg angles of 
the lower wires, it affects radiation very little.

ON4UN describes vertical loops in his book. Check out the loop-article on the 
aformentioned site as well. 

Despite what some people say I find that vertically polarised antennas work 
well.
