DB, I am a big supporter of the 1/4 wave radiating element with a suitable ground plane attached at a good height above ground.

And here are two models both at 32' feet showing the patterns, one is a 102" 1/4 wave radiator with 4 x 102" slanted down radials. The other is a standard looking 5/8 wave with 4 x 105" horizontal radials.

The difference in these patterns, if correct, symbolizes the advantage that a 1/4 wave could have over a 5/8 wave under the right conditions. With the 5/8 wave pattern, every angle above 11* degrees, 2 degrees above its maximum angle, will present 50%-100% less RF due to its narrow lobe shape. That is the point I make.

However, there are lots of other factors to consider, but the shape and magnitude of the maximum working surface of these patterns has to be considered as well...when DX is coming in at all kinds of angles with reflected sky waves.

Just something to consider.
