• General recommendations for lightning protection on masts

2 or 3 meter masts can be equipped with a lightning rod which is installed on top of the mast, and a grounding rod which is clamped to the foot of the mast. This creates a protected space in a 45 degree angle from the tip.
 
 

• General recommendations for lightning protection of enclosures

Surge protection devices are installed in one corner inside the measuring enclosure. All lines to and from the surge protection devices should not run parallel.
 
 

• General system protection of stations with enclosure and mast

Lines to equalize drops in the electrical potential between mast and grounding rod are installed 50 cm below the soil surface.
 
 

• General lightning protection with grounding rods

According to the standards the ground rod (diam. 25 mm) must be inserted into the ground for a minimum of 2,5 meters below the frost level, i. e. at least 3 meters. Crosswise shaped rods are less advisable for such low depths, but this depends on soil type, moisture or clay content, and distance between soil surface and ground water level.
 
National standards about the potential equalization and the surge protection of electronic systems and facilities should always be consulted and obeyed.
