A. For a path over water at 2.4Ghz, you only need to make sure that you have 100% first fresnel zone clearance over the entire path, and that you have a minimum of 10 dB fade margin, plus approximately 0.5 dB of added margin per km. of path length. Use Alvarion link budget calculation spreadsheets, which will recommend the correct fade margin based on the distance entered. You may need to increase the fade margin even more if very heavy rain is often encountered over the link.
