WI-I/O 9-L-x Installation Guide This section explains how to install your antenna and contains the following sections: Section Description For more information, see … Supported antennas and cables Details the antennas and cables you can use with the units. Supported antennas on page 12. Radio transmission distances Details the distances for reliable operation. Radio transmission distances on page 14.
WI-I/O 9-L-x Installation Guide You must carefully select antennas for WI-I/O 9-L-T modules to avoid contravening the maximum power limit on the unlicensed channel. The net gain of the antenna/cable configuration should be no more than 6dB in North America (USA, Canada, Mexico) and no more than 0 dB in Australia / New Zealand. Note The net gain of an antenna/cable configuration is the gain of the antenna (in dBi) less the loss in the coaxial cable (in dB).
WI-I/O 9-L-x Installation Guide The unit will operate reliably over large distances depending on the: Antenna type; Antenna location; Amount of radio interference; and Radio path obstructions (e.g. hills or trees). Typical reliable distances are: Area Distance Additional information USA/Canada 20+ miles 6dB net gain antenna configuration permitted (4W Equivalent RF power permitted). Australia/NZ 20+ km Unity gain antenna configuration (1W Equivalent RF power permitted).
WI-I/O 9-L-x Installation Guide You must connect an antenna to each WI-I/O 9-x module using the SMA connector at the top of the enclosure. Weidmuller Inc. recommends carefully taping the connections between the antenna and coaxial cable to prevent moisture ingress. Moisture ingress in the coaxial cable is a common cause of radio system problem as it greatly increases the radio losses. Weidmuller Inc. recommends taping the connection with three layers of tape: Layer Tape 1 PVC tape.
WI-I/O 9-L-x Installation Guide This section contains important information for using dipole and collinear antennas. For more information, see the next sections. Unity gain dipole antennas are commonly used on unlicensed channels. The dipole antenna does not provide any gain, so the power transmitted from the antenna is the same as the power out of the module. A dipole antenna that comes supplied with integral 15 ft cable does not require additional coaxial cable.
WI-I/O 9-L-x Installation Guide The following diagrams shows the recommended installation for collinear and dipole antennas: WI-I/O 9-L-x v1.
WI-I/O 9-L-x Installation Guide Yagi antennas are directional and have positive gain to the front of the antenna and negative gain in other directions. You can use the gain to: Compensate for coaxial cable loss for transmitter unit; and Increase receive sensitivity for receiver units. You should install Yagi antennas with the central beam horizontal and pointed directly in the transmission direction to benefit from the antenna gain. Note Yagi antennas usually have a drain hole on the folded element.
