2.4 link signal strength
I have a first class project in tow to put a 2.4GHz link in to the club about 4.5 miles away. I’ve just secured 5 grid dishes with 24dbi of gain for £125. What is a Fresnal zone and how do I spell it?
Anyway, there’s this great site to calculate the potential likelihood of succeeding in putting a link up between one site and another: http://www.atdi.uk.com/WebObjX/default.asp. It also gives you the dreaded Fresnel Ellipse data which I think I’m slowly starting to understand - essentially, you can block around 40% of the ellipse in one place and the link should still work, but no more. Google it for more.
