NOTE 1 For 80 MHz the higher value is valid.
NOTE 2 These regulations may not apply in all situations. The propagation of electromagnetic waves is influenced by the
absorption and reflection by building, objects and persons.
a
The field intensity of stationary transmitters, such as base stations of radiophones and land mobile services, amateur
stations, AM- and FM-radio and television stations can theoretically not be exactly predetermined. In order to determine the
electromagnetic environment and the effect of stationary HF transmitters, it is recommend to examine the corresponding
location. If the detected field intensity at the location of the Kröber O2exceeds the compatibility level specified above, the
Kröber O2must be examined at a different location, with respect to its normal operation. If unusual performance
characteristics are detected, it may be necessary to apply additional measures, such as reorientation or relocation of the
Kröber O2.
b
Beyond the frequency range from 150 kHz to 80 MHz the field intensity is less than 3 V/m.

Portable and mobile radio
equipment should not be

used closer to the
O2
and the leads, than the
safety distance calculated
by using the equation
applicable for the
transmission frequency.
Recommended safety
distance:
d= 1.2 √P for 80 MHz to
800 MHz
d= 2.3 √P for 800 MHz to
2.5 GHz
d= 1.2 √P
with P being the rated
power of the transmitter in
Watt (W) acc. to the
specifications of the
transmitter manufacturer
and d being the
recommended safety
distance in metres (m).
According to an in-situ
a
examination the field
intensity of stationary radio
transmitters is with all
frequencies lower than the
b
compatibility level .
