  • Q & A

    How much cable comes with the paddles? How far from the wireless unit can you get?


    Thank you for your inquiry. No cable is provided. A BNC to BNC 50 Ohm cable is needed. Generally up to 100 feet is acceptable before significant signal loss.


    Good morning, I installed 2 antennas on the ceiling of a conference hall. Also upstairs there is a conference room, but above there are shady areas where microphones are not receiving well. How can I better direct the antennas? Now they are vertically. Thank you


    You may contact Audio-Technica Europe for further assistance.


    If antenna power is turned on (i.e. in a wireless receiver or ATW-DA49) and a passive antenna (i.e. ATW-A49 or whip antenna) is connected, can the antenna power cause damage to the passive antenna?


    Thank you for your inquiry. No, it will cause no damage.


    Does an ATW-R3100bi require a pair, or will the pair support 2 receivers?


    The ATW-A49 come as a pair and each receiver should have two antenna for True Diversity. You may use devices such as the ATW-49SP or ATW-DA49 Antenna Distribution which allow you to connect multiple receivers to a single pair of antenna.


    Do these antennas need to be at the same height, or could one be mounted two feet higher than the other one?


    They do not need to be mounted at the same height and should be setup to keep your true diversity.


    Is there a specific direction these paddles should point? Is there a Front or Back ? How do you Aim the paddles?


    The shorter dimension is the front, and the antenna should be oriented vertically. The back of the antenna is where the BNC antenna cable connector is located. Point the front of the antennas toward the microphone/transmitter. The ATW-A49 Antennas are quite directional (providing 6 dB of gain). There is no pickup from the rear and little pick up from the sides.


    Is there such a thing as a travel case for these paddles?


    Thank you for your inquiry. No, there is not.


    We are installing these in a gym. Do you have any type of "guard" that would work with these?


    Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this.


    Can I install the ATW-A49 Antenna, outside?


    Please contact our Audio Solutions Department at (330) 686-2600 ext 5000 or at for assistance with this.


    Would there ever be a need to use the optional 12VDC antenna power with these? Or should I keep that switch off?


    The ATH-A49 is passive and does not require antenna power.
