When installing isolated air-termination systems for Frequency [F] Wave length [ ]
omnidirectional antennas, it has to be considered that an isolated
air-termination rod with a sufficient protective angle covers the 100 000 3000
antenna to be protected. Furthermore it has to be ensured that 1 000 000 300
sufficient separation distance is maintained.

From a functional point of view, a distance has to be kept 80 x 10 6 3.75
between the antenna and the air-termination system, which 100 x 10 6 3
corresponds to a quarter of the wave length of the radio 6
frequency used. The installation conditions according to 160 x 10 1.875
installation instructions No. 1521 have to be observed. 900 x 10 6 0.33
