2.3 DC Power Injector
The Cat 5 DC Power Injector is not in a waterproof enclosure and must be protected from the
weather. It can be permanently mounted to a surface using the double stick tape found on the
back of it.
2.4 Power Supply
The EtherAnt II antenna kit normally comes with a 110VAC power supply that has a standard
barrel plug [center pin positive (+) tip and outer ring negative (-)]. (220 VAC power supplies are
available as an option.) Although normally provided with a power supply, any power source
meeting the following specifications can be used:
EtherAnt II 12-24VDC @ 500 mA maximum cable length: 300 feet
EtherAnt II-LR 15VDC @ 1300 mA maximum cable length: 100 feet
CAUTION: Operating the EtherAnt-LR version with more than 15 VDC will damage it.
Operating it with less than 15 VDC will cause improper operation.
2.5 Aiming Antenna and Checking Signal Strength
The EtherAnt II has signal strength indicator, which can be monitored by the Client Manager
software to help optimize the aiming of the antenna. If you are using an Orinoco or YDI Access
Point in your wireless network, you can also use the Link Test capability of the AP Manager
software to monitor the signal strength of the Ether Ant II into the base unit.
Figure 2.1. Outdoor Pole Mount Installation
Figure 2.1 shows the antenna in typical
horizontally polarized installation. It must be
carefully aimed at the base antenna and be
mounted with the same polarization. The
housing is sealed to prevent water from entering
the antenna. The round connector must also be
sealed after it is plugged into the antenna. Be
sure to provide strain relief the Ethernet cable as
well.
If this EtherAnt II antenna is aimed at a
vertically polarized omni-directional or sector
base station antenna, it must be mounted
vertically polarized using the other mounting
stud on the back.
