1) In this country the use of 80 MHz channel width is not permitted in the channels 52 to 140.
2) Maximum permissible gain: Antenna and additional attenuation elements
Maximum permissible gain: Antenna and additional attenuation elements
When using antennas with a very high antenna gain, the maximum permitted EIRP
(equivalent isotropic radiated power) of the device is often exceeded even at minimum
transmit power. Additional attenuation elements must therefore be used between the
device and the antennas. The "Max. permitted gain" column in the table above shows the
maximum permitted antenna gain (total value) that can be connected to the antenna
sockets of the devices. If the typical antenna gain of the antennas to be connected
exceeds the maximum permissible value, you must compensate for the difference by
using attenuation elements, for example, an attenuator or connecting cables.
The following table provides an overview of possible attenuation elements and their
attenuation values:
Name
Attenuator
Antenna connecting cable, 1 m long
Antenna connecting cable, 2 m long
Antenna connecting cable, 5 m long
Example
The antenna ANT793-8DL is used.
• Typical antenna gain: 14 dBi
• Maximum permissible gain for channel 36 in Germany: 11 dBi
In this case the typical antenna gain exceeds the maximum permissible gain by 3 dBi.
This means you must use an attenuation element with at least 3 dB. This can be a
connecting cable, for example, with a length of 5 meters.
