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.
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.
