Der Sender SER 1 gestattet in Verbin-dung mit einem hochwertigen Empfän-
ger, z. B. unserer Type ER 3, den Auf-
bau einer drahtlosen Obertragungs-
einrichtung für mittlere Reichweiten. Die Reichweite ist abhängig vom An-
tennenaufwand der Empfangs- und
Sendestation und beträgt im ebenen Gelände bei Benutzung von
Tragriemenantenne am Sender und
Mit mehreren Sendern lassen sich
Relaisstrecken aufbauen, wobei zweck-
mäßig stärker bündelnde Antennen
verwendet werden, weil die Relais- stationen ortsfest sind. Für den Bedarf
der deutschen Rundfunkanstalten sind 2 Frequenzen im
Außerdem ist für Fernsteuer- und Fern-
wirkzwecke eine Tonmodulation über
den Leitungseingang möglich.
Dieser Eingang steht auch für draht-
lose Datenübertragung zur Verfügung,
wenn die Daten so aufbereitet sind, daß sie in den Obertragungsbereich des Senders passen.
Es ist natürlich auch möglich, den Sen-

4. Application
The transmitter SER 1 in conjunction with a high quality receiver (e. g. Senn- heiser receiver ER 3) allows the set up
of a wireless transmission system to
cover medium distances. The usable range depends on the antenna systems
employed with the transmitter and the receiver. The following distances can
be achieved over flat ground:
Approx. 1 km using the shoulder strap
antenna at the transmitter and a )J4 rod antenna at 1.5 m above ground at the receiver.
Approx. 1.5 km using )J4 antennae a1C'"
1.5m above ground at transmitter and receiver.
Approx. 2 km using the shoulder strap
antenna at the transmitter and a )J2
dipole at 3 m above ground at the re- ceiver.
Approx. 3 km using a i.l4 rod antenna
at the transmitter and a )j2 dipole at 3 m above ground at the receiver.
Approx. 6 km using a i.l4 rod antenna
at the transmitter and a )j2 dipole at 10 m above ground at the receiver.
Approx. 20 km using a )J2 dipole (3 m
above ground) at the transmitter (sta-
tionary operation) and a )j2. dipole (10 m above ground) at the receiver.
Consequently the transmitter can be used as an intensified wireless micro-
phone for location work of radio and
TV broadcasting stations. The transmission quality meets broadcast stand-
ards. | also |
