Recommended Separation Distances between Portable and Mobile HF Communications Equipment and the device or system
Recommended Separation Distances Between Portable and Mobile HF Communications Equipment
and the KaWe examination lamp
The KaWe examination lamp is intended for use in an electromagnetic environment in which radiated HF disturbances are controlled. The
customer or the user of the equipment can help prevent electromagnetic interference by ensuring that the minimum distance (shown
below) between communications equipment (transmitters) and the KaWe examination lamp is maintained. The minimum distance is
dependent on the maximum output power and the frequency of the communications equipment.

For transmitters with a maximum rated output not specified in the above table, the recommended separation distance (d) can be deter-
mined in meters (m) using the equation for each column, where the maximum rated power (P) of the transmitter is in watts (W) as given by
the transmitter manufacturer.
Note 1:
For 80 MHz and 800 MHz, the larger of the two values applies.
Note 2:
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.
