The conditions detailed in the EN 50083-1 must be ob-
served when mounting antennas on a mast.
The sum of the moments resulting from the intrinsic mo-
ment of the mast and the bending moments caused by
the mounted antennas must not exceed the maximum
permitted bending moments of the mast itself.
The bending moment caused by an antenna is calculated
by the following formula:
Wind load (N) x distance (m) = bending moment (Nm)
The distance and bending moment refer to the top
clamping point. Bending moments in excess of 1650 Nm
require proof of structural stability.
Wind load x distance = bending moment
1)
16 N x 3,6 m = 57.6 Nm
2)
56 N x 2,8 m = 156.8 Nm
3)
96 N x 2,0 m = 192,0 Nm
4)
619 N x 1 m = 619,0 Nm
Total bending moment of the antennas 1025,4 Nm
The total bending moment for the antenna at 1025.4 Nm
is less than the usable bending moment for the antenna to
be mounted of 1250 Nm.
Therefore the intended configuration is permitted!
In accordance with DIN EN 50083-1
the clamped length of the mast must
be at least 1/6 of the mast length
