CAUTION
•
Close proximity to the donor or server antennas with the Signal
Booster in operation may expose users or installers to RF fields that
exceed FCC limits for human exposure.
•
Turn power to the Signal Booster off when connecting or disconnecting
cables.
•
Be careful as there is a very high voltage inside Signal Booster. Key is
required to open Signal Booster, but the key must be kept by the
administrator who manages the product.
5.2 Donor Antenna Installation Guidelines
•
Accurately determine the azimuth to the donor site. Obtain the donor site information and
approval from the service provider/carrier.
•
Ensure that the radiation path to the donor site is unobstructed.
•
Mount the donor antenna at or toward the edge of the roof, in the direction of the donor
site. Avoid having the RF signal from the donor pass above the location(s) of the service
antennas. Normally, the service antennas are installed behind and below the donor antenna,
as viewed from above. This approach helps avoid interference and feedback to and from the
service antennas.
•
Normally, mounting the donor antenna higher will allow a less obstructed path to the donor
site. However, in high traffic metro areas, avoid mounting the donor antenna higher than
necessary, as the quality of the donor signal may become less stable and it is more likely to
encounter adjacent channel interference.
•
When possible, shield the rear of a donor antenna by locating it so that any HVAC units
and/or penthouse structures are behind the antenna, relative to the donor cell site location.
