INSTALLATION
2.1 Locating the EtherAnt II
The most important aspect of setting up the EtherAnt II is its location and aiming. It must have
clear, unobstructed line of site between it and the base station antenna or the other wireless
device it is talking to. If there are any obstacles in the way, it will not get a reliable wireless
connection. The EtherAnt II should be installed outdoors, but can be located in a window if
necessary. However, for maximum range and the strongest signal, the EtherAnt II must “see”
the base station antenna in order to be connected. If they do not have this clear line of sight
(LOS), you will likely not get a wireless connection.
2.2 Mounting the EtherAnt II
The antenna can be mounted either vertically or horizontally polarized using the hardware
included with the unit. Refer to the polarization arrow on the back label of the antenna. Please
note that both ends of the link must use the same polarization. It can be mounted to a mast or
pipe as shown in Figure 2.1 or to a flat surface such as a wall. Note that most omni antennas are
vertically polarized and if the EtherAnt II is aimed at one, it must be installed vertically
polarized, i.e. with the Polarization arrow up and down.
It is very important that the Ethernet connector on the antenna be properly waterproofed. Ensure
that a high quality weather resistant electrical tape and/or other water sealant method is utilized.
Silicon sealants are not recommended since they are hard to work with, do not ensure a 100%
waterproofing of the connectors and are difficult to remove, if ever necessary.
Safety Warning
CAUTION
This antenna/transmitter device must be fixed-mounted on outdoor
p
ermanent structures with a separation distance of at least 2 meters
f
rom all persons. Users and installers must adhere to the antenna
installation instructions and transmitter operating conditions in order
to comply with the FCC’s RF exposure requirements.
