The first Fresnel zone size is a list; Proxim’s recommendation is to keep at least 60-70% of this zone free. If the clearance is lower than this percentage, the link budget and achieved fade margin are affected.

Clearances more than 100% of the Fresnel zone can cause reflections that are 180 degrees out of phase and can cancel out the signal. The Fresnel zone works in both the horizontal and vertical paths.

*17.4dBm is the FCC certified peak output power of Tsunami MP.11a product at 5.25-5.35GHz band

**20.8dBm is the FCC certified peak output power of Tsunami MP.11a product at 5.725-5.850 GHz band

These power levels are the levels at the antenna connector of the MP.11, so where the MP.11 has a higher output power than certified, the TPC needs to be used to reduce the output power.
