hi guys:

I am looking for info in order to calculate a line-of-sight datalink via a sea path. VHF/UHF range. Any equations, books, links are welcome

Re: sea propagation

If this is over the water, you will want the first Fresnel zone to clear the water.

**broken link removed** has some charts and http://www.softwright.com/faq/engineering/Fresnel Zone Clearance.html has the equation you can program on a spread sheet.
