Connecting antennas

If you are using more than one transmitter, we recommend using remote antennas and the AC 3200-II antenna combiner.
You can find more information here:

For professional use, we recommend connecting a remote antenna and, if necessary, using Sennheiser antenna accessories.

If the transmitter is to be put into operation without a large amount of installation work, you can:
  • connect the supplied rod antenna to the rear of the transmitter
  • use the optional GA 3030 AM antenna front mount kit.
Connecting and positioning a remote antenna
Use a remote antenna when the transmitter position is not the best antenna position for optimum transmission. You can choose between two antennas (see Accessories):
  • A 2003 UHF passive directional broadband antenna
  • A 1031 passive omni-directional broadband antenna
  1. Use a low-attenuation 50 Ω cable to connect the antenna to the transmitter.
  2. If possible, use a short antenna cable and as little connections as possible, since long cables and many connectors lead to an attenuation of the antenna signal.
  3. Position the antenna in the same room in which the transmission takes place.
  4. Observe a minimum distance of 1 m between the antenna and metal objects (including reinforced concrete walls).

Connecting several transmitters to a remote antenna
To make multi-channel systems, you should use the AC 3200 antenna combiner (optional accessory). The AC 3200 allows you to operate up to eight transmitters with a single antenna without virtually any intermodulation.
  1. Connect the AC 3200 antenna combiner to the BNC socket (see Connecting the AC 3200-II with transmitters).
To connect the rod antenna to the rear of the transmitter:
The supplied rod antenna & is suitable for all applications where the transmitter is to be put into operation without a large amount of installation work.
  1. Connect the rod antenna to the BNC socket RF OUT on the rear panel of the SR 2000 IEM / SR 2050 IEM transmitter.
To mounting the antennas to the front of the rack:
To mount the antenna connections to the front of the rack when rack mounting the transmitter, you require the GA 3030 AM antenna front mount kit (Antennas and accessories).
  1. Guide the BNC connector of the BNC extension cable through the hole in the rack mount “ear”.
  2. Connect the BNC connector to the antenna output.
  3. Screw the antenna holder to the BNC socket using the supplied washer and nut.
  4. Secure the antenna holder to the rack mount “ear” of the transmitter using two of the supplied screws.

    If you are using the SR 2050 IEM twin transmitter:

  5. Mount the second BNC extension cable in the same way.
  6. Slide the transmitter into the 19" rack.
  7. Connect the rod antennas to the two BNC sockets.
