Protection against lateral impact
From building height and the risk serious
damage (e. bal-
conies, cameras, antennas, etc. with electrical electronic devices) is
advisable install ring circuit protect against lat-
eral impact.g.g.).
When the lateral impact method used, the position-
ing the air-termination unit sufficient when all the
parts the element protected are under sur-
face, which created straight line with angle
of 15º the vertical. However, elements protruding
over the building dimensions may risk (e.g
