strike damage. It is possible however, to reduce the likelihood of damage from near strike induced
fields by ensuring the installation obeys some fundamental rules.
A proprietary lightning arrestor should be installed, of a type which does not reduce GNSS
signal transfer. Install the lightning arrestor near to the antenna (e.g. on the mounting pole),
ensuring all connections maintain electrical and environmental protection.
After taking the precautions described previously in the antenna installation, it should be
understood that a destructive residual current may still be present in the cable coming down from
the antenna to the
NTS-pico3
unit.
A second lightning arrestor should be installed near to the
NTS-pico3
to further dissipate any
remaining lightning energy. At the earth end please use multiple connection points if at all possible.
All connections should incorporate as large an area of contact as possible, which is made
more probable using large bolts, and substantial washers. Where there is no access to the metal
framework of the building, it is imperative to erect a suitable lightning conductor. Failure to do so
is almost certain to result in destruction of
NTS-pico3
and connected into it equipment in the event
of the antenna receiving a near lightning strike.
