3)
1) In this country the use of 80 MHz channel width is not permitted in the channels 52 to 140.
2) The antennas ANT793-8DJ, ANT793-8DK, ANT793-8DL and ANT793-8DP must not be used for the SRD channels 149 to
165.
3) The use of RCoax is not permitted.
Note on the use of ANT792-8DN, ANT793-8DJ, ANT793-8DK, ANT793-8DL and ANT793-8DP
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 column "MaxAntGain" 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.
