l
If there are radio systems at the site that are already operating on
the 450 - 470 MHz band, it may be advantageous to combine the
signals into one antenna system using the appropriate equipment.
This often works better than attempting to protect the individual
systems from interfering with each other.
l
Managed antenna sites may require additional equipment and may
dictate how an installation is to be performed. As long as the
installation meets Neptune's minimum requirements, following the
site's requirements is recommended.
Feed Line and Antenna Recommendations
CAUTION: Neptune recommends that you consult with a
qualified installer on the design and installation of the
antenna systems. If the installer is already familiar with the
sites and the existing equipment, this can make the
installation go more smoothly.
MISE en GARDE: Neptune vous recommande de consulter
un installateur qualifié pour la conception et l’installation
des systèmes d’antennes. Si l’installateur connaît déjà les
sites et les équipements existants, cela peut faciliter le
déroulement de l’installation.
Feed Line
The feed line is a significant contributor to both good and poor
system performance. A properly installed feed line is critical to
optimal system performance. Testing the antenna while it is on the
ground can ensure the system is working properly.
Installation of the connectors is best done with the proper tools and a
trained installer. With the proper tools and jigs, installing coaxial
(coax) connectors takes only a few minutes each. Not using the proper
tools as recommended by the manufacturer could potentially cause
problems, either immediately or after several years of apparently
proper operation.
Feed Line Requirements
Consider the following.
l
The antenna and feed line system installation must be certified by
the installer after it is completed to perform according to
specifications.
