Installation & Connection
●
Connecting the antenna extension cable (WE70-CA5M)
The cable length of the magnet base antenna is 2m. If longer length is required, use the antenna
extension cable (WE70-CA5M) 5m. Pay attention to attenuation of the cable when using the antenna
extension cable.
●
Precautions on Using Magnetic-base Antenna & Antenna extension cable
Using a magnetic-base antenna causes signal attenuation due to its cable, reducing communication range
compared with a standard pencil antenna.
Using Magnetic-base Antenna on Client
In an example below, receiving electric field strength decreases in the 5GHz band by up to 8
levels.Degree of decrease is larger in the 5GHz band that uses higher frequency than the 2.4GHz
band.To use a magnetic-base antenna, a communication range should take cable attenuation into account
for actual receiving electric field strength of a pencil antenna.
Using Magnetic-base Antenna on Access Point & Client
Using magnetic-base antennas & Antenna extension cable causes signal attenuation by up to 6 levels in
the 5GHz band, compared with a pencil antenna (accessory).If magnetic pedestal antennas are used for
both of an access point and a client in the 5GHz band, it is necessary to ensure additional 6 levels of
received field intensity to gain the same level of received field intensity as that of a pencil antenna.
Caution
• Holding or pulling an antenna while uninstalling may damage it.
• Always hold the base part for handling.
• Avoid cable twisting as long as possible.
• Before attaching it to a wireless unit, check if the plug and the jack are properly coupled, and tighten a ring nut.For
installation, turn the ring nut only while keeping a cable unturned.
• Take precautions so that a cable should not be damaged by a hole edge while putting it into the hole.
• Using a magnetic base antenna causes signal attenuation due to its cable, reducing communication range compared
with a standard pencil antenna.

Precautions for Antenna Installation Location
This wireless unit set uses very high radio frequencies of 2.4/5GHz.High frequency radio wave is progres-
sive and reflective.
To ensure wireless performance, it is necessary to choose an appropriate location for antenna installation.
For co-polarization of each antenna, see "Appendices-3 Antenna".
