Antenna Attenuator
» Antenna Attenuator Function
This function decreases the antenna reception sensitivity so as to minimize reception of distant
interference radio signals.
•When to use this function
Use this function when radio interference or signal interruption caused by the interference of other systems
intermittently occurs.
Note: Since the use of an attenuator shortens the transmission distance and reduces the range of the usable
area, ensure that the microphone can be used without signal interruption in the intended usage area after
performing settings.
The attenuator can effectively reduce interference signals if they are relatively weak. The most effective results
may not be obtained when interference signals are strong (i.e. when audio interference constantly occurs).
•Proper use of two attenuators
Use either the WT-D5800 or YW-4500 attenuator to attenuate the reception sensitivity by 10dB. The WT-
D5800 may be more convenient as it allows settings by hand.
Since the attenuation of both the YW-4500 and WT-D5800 attenuators are added together, when
wishing to attenuate reception sensitivity by at least 10dB, use both attenuators in combination.
(This is a rare case, though.)
