Installing the 3CRWEASYG73 Outdoor Wireless Bridge
Mount the Unit to a Mast
Follow the instructions that come with the bridge mounting hardware and follow the
general guidelines listed below.
NOTE:
Mast should extend above bridge 1
meter (3 ft)
Recommended Pole Diameter
= 2” – 2.5”
Maximum Pole Diameter = 3”
Bridge may be installed to
freestanding or roof mounted mast
♦
For best performance, place the antenna outdoors using the mounting
hardware provided with the antenna. Placement is especially important if the
building is of metal construction or has metal siding. If necessary, you can
mount an antenna inside a building; however, indoor placement reduces the
antenna’s effective range.
♦
To ensure the physical safety of anyone near the antenna and to prevent
damage to the bridge, follow the building codes for antenna installations in your
area. This is another good reason to make sure that only a professional
performs the installation.
♦
Keep in mind that in order to comply with FCC radio-frequency radiation
exposure guidelines, a minimum body to antenna distance of 2 meters (6 feet)
must be maintained while operating this device.
♦
Ensure that access is available for routing the Ethernet cable from the bridge to
the Ethernet connection inside.
♦
Make certain that the antenna mast is appropriately grounded. Proper
grounding can prevent injury or damage from lightning strikes.
♦
After installing the bridge, the highest allowable power level is automatically set
when country selection is configured. Adhering to this configuration ensures
compliance with national laws.
