Re: [HCDX]: Re: Beverages

Fellow DX-ers,
I have been reading with some interest the stories about Beverage antennas. 
Compared to elk, snakes, etc, life is rather dull here, with nothing bigger than 
a sparrow resting on my antenna, or a mouse or an occasional rat wandering 
through my garden (at the border of a small SW German city, no chance to get up 
anything close to a true long wire)
My question is maybe a bit stupid, but from what length on does a "normal" long 
wire become a directional Beverage ? 0.5, 1.0 or 2.0 wavelength, or even more ?
I have no experience whatsoever with such long wires (15 m is all I can get at 
my neigborhood), and I was planning some mobile AM-DX (daytime to start with) 
from my car up in the Black Forest mountains, just in my backyard so to speak. 
(sorry, no elk or dangerous snakes there either, so do not expect good stories). 
I have now prepared some 100m of wire to use, but this is still much less than 
1.0 wavelength for mediumwave. I have no clue if this already gives some 
directionality. In principle I can extend the wire at will. I have located a 
parking place where I would be able to lay a few 100m out (direction west). But 
thinking of re-winding it again, I do not want to overdo things.
Any experience ?
