Comment Re:3.1GHZ Has trouble going through walls (Score 2, Insightful) 139

It's extremely difficult to gauge foliage attenuation. It literally varies as the wind blows. Because of the wavelength, 5.8GHz also requires less fresnel zone clearance compared to 2.4GHz so if you were skimming the top of the trees on a marginal link, the blockage at 2.4GHz would be more severe, perhaps enough to dip you below the required signal-to-noise ratio.

If the trees were dense and the power ouput the same then 2.4GHz would win out.
