Putting the transmitter into operation
9
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” on
page 23):
• A 2003 UHF passive directional broadband antenna
• A 1031 passive omni-directional broadband antenna
̈
Use a low-attenuation 50-
Ω cable to connect the antenna to the transmitter.
̈
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.
̈
Position the antenna in the same room in which the transmission takes place.
̈
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.

Connect the AC 3200 antenna combiner to the BNC socket ƽ .
Connecting the rod antenna to the rear of the transmitter
The supplied rod antenna
ƾ
is suitable for all applications where the transmitter is to be put
into operation without a large amount of installation work.

Mounting the antennas to the front of the rack
To mount the antenna connections to the front of the rack when rack mounting the trans-
mitter, you require the GA 3030 AM antenna front mount kit (optional accessory).
The GA 3030 AM consists of:
• 2 BNC extension cables (screw-in BNC socket
ƿ
to BNC connector ),
• 2 antenna holders ,
• 4 screws,
• 2 washers ,
• 2 nuts .
You can connect several transmitters to the same remote antenna (see next section).
