Fresnel zone question

[warlock072]

does the fresnel zone increase if u got a more powerful antenna??? or does it decrease???

I just love wiki http://en.wikipedia.org/wiki/Line-of-sight_propagation

Warlock what makes you ask this question ?

I was just kinda wondering about it when i was on the roof of a friends house doing wug stuff. Noticed that a house not to far way from him (high up than him) which im guessing is cause some ccq issues. currently has a 3m pole. grid to grid. 24db myside and 27 his side. was wondering of this could be the issue!?

I read the wiki article and my knowledge says the Frenel zone does not change. Better ant will always give better signal.

What was the distance ? Grid to grid should be easy, unless someone is using that frequency.

We talking roughly 8km. To me that makes sense better ant better signal. On WIND when u switch freq between 2.4ghz and 5ghz then the fresnel zone thins out, and saying that better ant equals better signal then I have to assume the ant does affect fresnel zone somehow!!!
