Use this information to correctly configure the product (using the UI) to avoid operation on
channels that must be avoided according to the guidelines that are contained in the KDB and
explained in detail in this user guide.
l
In ETSI regions, the band 5600 MHz to 5650 MHz is reserved for the use of weather radars.
Ethernet networking skills

Lightning protection guidelines
To protect outdoor radio installations from the impact of lightning strikes, the installer must be familiar
with the normal procedures for site selection, bonding and grounding.
Warning
Electro-Magnetic Discharge (EMD) lightning damage is not covered under
warranty. The recommendations in this section, when followed correctly,
provides the user the best protection from the harmful effects of EMD. However,
100% protection is neither implied nor possible.
Purpose
To protect structures, equipment and people against power surges (typically caused by lightning) by
conducting the surge current to ground via a separate preferential solid path. The actual degree of
protection required depends on local conditions and applicable local regulations. Cambium recommends
cnPilot installation is contracted to a professional installer.
Standards
Refer international standards IEC 62305-1 and IEC 62304-4, the U.S. National Electric Code ANSI/NFPA
No. 70-2017 or section 54 of the Canadian Electric Code for details of lightning protection methods and
requirements.
Lightning protection installation zones
The “Rolling sphere method” is used to determine the safe zone to install the lightning protection
equipment. An imaginary sphere, typically 50 meters in radius is rolled over the structure. Where the
sphere rests against the ground and a strike termination device (such as a finial or ground bar), all the
space under the sphere is in the zone of protection (Zone B) as shown in
. Similarly, where the
sphere rests on two finals, the space under the sphere is considered as in the zone of protection.
