Fresnel zone intrusion

If have Fresnel zone computations active, you can get a graph of the intrusion of the terrain by right clicking on the LOS window.

Intrusion of 100% completely blocks the first Fresnel zone, and 0% leaves the entire zone free.

Graph showing  percentage intrusion into the first Fresnel zone.

There is intrusion into the outer 30% of the zone within the first 100 m, and then a hill that actually blocks the entire LOS and the entire Fresnel zone at about 2.5 km.
