In addition, and where applicable, we recommend following the IEC 61024/ IEC 62305 standards for
proper lightning protection and install the antennas within the lightning protection zone LPZ O
B
where
the equipment is not subject to direct lightning strikes (See Fig. 3-7).
1 IEC 61024 When the linkhead is located near another grounded/earthed object, such as a tower, lightning
(Franklin) rod or any type of mast or pole, it may fall under the zone of protection provided by the tower
or mast.
Even if it is not under the Zone, if it is not a good path to ground/earth it is less likely to be destroyed by
lightning.
2 High Lightning zones It is possible to deliberately place a protective mast near the linkhead to provide this type of zone. In
this case the linkhead is protected by the mast and is further protected by not being a good path to
ground/earth for the lightning.
The mast should have a sharp point at the top. This encourages the formation of the lightning strike
where the electrons are concentrated at the tip of the rod and further protects the equipment
3 Towers A linkhead mounted on a tower is almost always within the LPZ O
B
zone and has some protection simply
because of its location.
