Installation Environment 2.3
2.3.1 Locational Requirements
Environments with high-temperatures, harmful gases, unstable voltages, volatile
vibrations, loud noises, flames, explosives, and electromagnetic interference (large radar
stations, transmitting stations, transformer substations) are not suitable for the operation
of Nova-243, and thus should be avoided.
Places prone to have impounded water, soaking, leakage, or condensation, should also
be avoided.
Factors like climate, hydrology, geology, earthquake, electric power, and transportation
should be taken into consideration in the construction process so that a proper location
can be chosen to meet the communication engineering environmental requirements, as
well as the technical requirements of network planning and communication equipment.

Install Antenna Feeder System 3.7
There are two kinds of outdoor antennas, omnidirectional outdoor antennas and
directional outdoor antennas, whose installation will be introduced in the following,
respectively.
3.7.1 Install Omnidirectional Antennas
One should pay attention to the followings while installing the omnidirectional outdoor
antenna:
The diameter of the pole for omnidirectional outdoor antennas is required to be
35mm ~ 50mm. A typical case is to use the 50mm-diameter round-steel-made pole
(with details depending on the specific antenna type).
Make sure that the top of pole and the clamp beneath the antenna are at the same
level, after installing the omnidirectional outdoor antenna on the pole.
Make sure that the antenna is high enough to meet the coverage requirement, and
that the antenna top falls within the 45 degrees safety angle towards the lightening
rod, as shown in Figure 3-5. In principle, no lightening rod can be welded to pole (no
metal object is allowed within 1m of the horizontal direction of the omnidirectional
antennas), when installing the omnidirectional antennas. Instead, an independent
lightening rod should be settled between the two poles, where the lightening rod
must be high enough to keep all antennas under its protection cover.
Figure 3-5 Omnidirectional Antenna Installation (1)
In case is impossible to install an independent lightning rod due to environmental
limitations, the installation method shown in Figure 3-6can be used. Be aware that the
pole supporting the lightening rod should be kept at least 1m away from the
omnidirectional outdoor antennas.
