Beyerdynamic WA-ATDA Datasheet

APPLICATIONS

The active WA-ATDA directional antenna is a receiving antenna for
indoor or outdoor use. It has a logarithmic periodic dipole field and
provides a better reception and suppression of interfering RF
signals from the rear than omnidirectional half-wave antennas due
to its lobe polar pattern.
The antenna operates in the UHF range between 470 and 1,000 MHz
and can be used with all wireless system with an antenna voltage
of 8 to 9 V such as the beyerdynamic series TG 1000. It is connected
via a BNC socket.
The WA-ATDA can be operated as a passive or active antenna with
a selectable gain of 6 or 12 dB. The selectable gain can compensate
cable loss.
The external voltage supply of 8-9 V DC is achieved via a coaxial
cable connected to a receiver or antenna splitter. An LED displays
the correct supply voltage. If the gain has been set to “passive”,
the antenna operates in the passive mode, for which a supply
voltage is required as well.
The antenna can be mounted on stands (3/8" or 5/8"), installed
hanging from a ceiling or attached to a wall by using the integrated
swivelling adapter.
For diversity operation two WA-ATDA antennas are required.

FEATURES

• Passive and active logarithmic periodic directional antenna for
the UHF range between 470 and 1,000 MHz

• Selectable gain of passive (0 dB), low gain (6 dB),
high gain (12 dB)

• Compatible to all receivers and antenna splitters, with a supply
voltage of 8 - 9 V DC

• Integrated thread adapter (3/8" or 5/8") for easy mounting to
microphone stands
