Connect the antenna
1 Connect one end of the antenna cable to the antenna.
2 Connect the free end of the antenna cable to the connection on the bridge.
Follow the instructions that come with the antenna and follow these general guidelines:
For best performance, place the antenna using the mounting hardware provided with the antenna. Outdoor
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.
Position the antenna so that there are minimal obstacles between it and any other antenna with which it will
communicate. While maintaining a direct line of sight between antennas is not strictly necessary, such an
arrangement helps to ensure a strong signal. Ensure that access is available for routing the antenna cable from the
antenna to the bridge. When mounting an antenna indoors, best performance can be achieved by mounting the
antenna near a window facing the opposite bridge.
Make certain that the antenna and antenna mast are appropriately grounded. Proper grounding prevents injury or
damage from lightning strikes.
