The Beyerdynamic active <b>WA-ATDA</b> 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.</p><p>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.</p><p>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.</p><p>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.</p><p>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 swiveling adapter.</p><p>For diversity operation two WA-ATDA antennas are required.</p>
