Installing Antennas
This section provides instructions for installing and connecting antennas. The antennas shown in this section
are a representative sample only and are provided as a guideline for installation—your specific antenna(s)
may be different, in which case refer to the instructions provided with the antenna(s).
Antenna Warning
Applying Power Before an Antenna is Connected
Strong RF Fields are Present
Notes About Antenna Installations
Read the following notes before installing any antenna.
◗
The system installer should always ensure that antenna radiation patterns do not overlap.
◗
A sector antenna should point towards the center of the sector covered by the antenna.
◗
Fixed point-to-point backhaul antennas should point towards the desired Strix Systems Access/One®
Network device intended for the backhaul connection.
◗
Unused antenna ports must be terminated with a 50 ohm terminator.
◗
Only antennas approved by Strix Systems (or equivalent) may be used with the Access/One® Network
Outdoor Wireless System (OWS).
◗
Only one antenna may be used on each antenna port.
◗
When installing antennas that require mounting brackets and U-bolts, it is easier to loosely attach the
U-bolts to the brackets, then slide the completed antenna assembly over the pole (instead of holding
the assembly against the pole and attaching each U-bolt separately—mounting brackets are shipped
with the U-bolts pre-assembled. For this reason, do not install an omni antenna at the top of the pole
before installing any directional/sectored antennas that will reside below it.
Antennas must be installed by a trained professional installer only.
Do not locate any antenna near overhead power lines or other electric light or power
circuits, or where the antenna can come into contact with such circuits. When
installing antennas, take extreme care not to come into contact with such electrical
circuits, as they can cause serious injury or death.
For the correct installation and grounding of antennas, please refer to national and local
codes (for example, US:NFPA 70, National Electrical Code, Article 810; in Canada:
Canadian Electrical Code, Section 54).
Do not apply power to the transmitter until the antenna is connected, otherwise
permanent damage may result.
When the unit is operation, avoid standing directly in front of the antenna. Strong RF
fields are present when the transmitter is ON.
