4. Installation
4.1. Environmental rating
Fluidmesh TUBE antennas are designed to withstand adverse
environmental conditions.
4.2. General installation practices to follow and avoid
When installing and adjusting an antenna in any scenario that uses
Fluidmesh hardware, install and adjust the antenna according to the
following recommendations.
NOTE
Not all recommendations listed in this section will apply to all
antennas.
• Make sure the antenna and its transceiver unit are properly
grounded (earthed) to prevent the antenna and transceiver from
accumulating static electricity or producing sparks. If the antenna
and/or transceiver are mounted in a flammable environment, stray
sparks could ignite the flammable materials, causing an explosion
and/or flash fire.
• Wherever practically possible, keep all antenna cabling runs under
10 feet (three metres). Radio signals conducted through antenna
cabling before being transmitted from an antenna suffer from a
phenomenon called signal attenuation. The signal gradually
dissipates along the length of the cable due to electrical resistance
before being transmitted from the antenna, reducing signal
amplitude.
• Do not bend or kink antenna cabling. Kinks and bends may cause
breaks and/or narrow points in the cable's electrical conductor,
resulting in degraded signal amplitude.
• Be sure to comply with the minimum and maximum co-location
distances specified by Fluidmesh for each antenna type. This helps
avoid co-location interference (in which the radio transmissions
from two or more antennas partially cancel each other out).
• Note that during test and adjustment of stationary antennas, an
antenna placement adjustment of between four and five feet (1.2m
to 1.5m) may be needed.
• A signal quality test and adjustment must always be done during an
installation to verify signal quality and amplitude. If the test and
adjustment procedure is not done, the installation is at risk of under-
performing due to poor line-of-sight and other factors.
• If applicable, avoid installing antennas inside audio loudspeaker
enclosures. The proximity of a radio antenna to the metal in
