    • Q:

      Is there a way to tighten the half wave antenna, so that it doesn't fall down when you position the antenna at 45 degrees?
      Asked on 6/16/2015 by PJones from Scottsboro, AL, USA

      1 answer

      • A:

        If the antenna is turning too easily inside its male BNC connector, no there is not a way to tighten it. Please contact our Parts Department for assistance obtaining a replacement antenna. Please note that if the antenna is one that was provided with a 4000 or 5000 Series Wireless System, the warranty on it is 5 years. If the antenna was purchased separately (model # ATW-A3C or A3D), the warranty period is 2 years. Please provide a copy of your dated sales receipt if claiming warranty replacement.

    • Q:

      Would these antennas work with my Audio-Technica ATW-R1810a system?

      Someone somehow lost one of them and I can't find any specific replacements for the 1800 series.

      • A:

        The stock replacement antennas will be available through the ATUS Parts Department, or because you're located in Canada, Jam Industries. To contact Jam for 1800 Series antennas, please call (514) 457-4875 or (877) 526-5463. To order them through the ATUS Parts Department, please call (330) 686-2600 x 5002. Other than that, it is not recommended to use the A3D / A3C 1/2 wave antennas directly on the 1800 Series Receivers.

        If you have any further questions, please include your original question and this answer, and email the Audio-Technica United States (ATUS) Audio Solutions Team, at audio-solutions@atus.com.

        Thanks!

    • Q:

      Which antenna is better to use, the half wave or quarter wave?
      Asked on 5/30/2015 by PJones from Scottsboro, AL, USA

      1 answer

      • A:

        The significant advantage of the half wave antenna over the quarter wave antenna is that it can be relocated away from the receiver simply by adding the needed length of 50 ohm RF antenna cable between the receiver and the antenna, and a BNC female to BNC female coupler to connect the cable to the antenna. The quarter wave antenna requires mounting to a metal plate that is roughly 12 x 12 inches in size. The plate provides the ground plane for the antenna which is lost when it is removed from the receiver chassis. Note that the feed-thru connectors used to attach the antenna cable to one side of the plate and the antenna to the other side of the plate, should be electrically connected to (not insulated from) the plate. Orient the antenna so that it is perpendicular to the plate, not parallel to it.

    • Q:

      Will this antenna work on the ATW-R3100b

      ours was broken off.
      Asked on 10/31/2012 by ddurbeck

      1 answer

      • A:

        It depends on the operating frequency band range of your particular ATW-R3100b Receiver. The ATW-A3C Half-wave Antennas are frequency band specific. They pass frequencies from 541.500 to 566.375 MHz only. This is known as the ''C'' band. If you have a C band Receiver, these antennas are compatible with it. Should you have a ''D'' band Receiver, which operates in the 655.500 to 680.375 MHz frequency band range, the ATW-A3D Half-wave Antennas pass frequencies in this band only. The same Quarter-wave antennas that were supplied with the Receiver are also available for purchase from the Parts Department.
