2.2. Assessment of the production environment
The exact observation and assessment of the production environment is the basic requirement to
ensure an ideal transmission.
» Which buildings and structures are located
in the surrounding area?
Radio signals are electromagnetic waves.
When these waves encounter an obstacle,
they will be reflected, attenuated or even
completely absorbed due to their physical
properties.
In general: The lower the frequency, the
better the penetration. The higher the
frequency, the worse the penetration.
» Which negative consequences result from
this?
Especially objects or structures made of
steel or metal can stop radio waves. This
also includes fences made of wire, steel
reinforcement in the masonry or metal
coated window panes.
Leaves from trees or bushes or rain or snow
as well lead to the attenuation or absorption
of the signal.
» Which positive effects does the
surrounding have for the transmission?
Smooth surfaces of buildings made of
masonry or reinforced concrete can be
used as reflection surfaces, in favor of the
transmission quality and range.

2.3. Alignment and positioning of the antennas
» Selection of appropriate antennas
Pay attention to the correct frequency
range! Short antennas are optimal for
mobile applications, but normally are less
sensitive. Long antennas are more sensitive,
but are not appropriate for mobile
applications, as the antenna socket is
exposed to a greater leverage when under
intense pressure and can be damaged as a
result of this.
» Pay attention - if possible - to the identical
altitude of transmission and reception
antennas.
4dB Antenna
6dB Antenna
» Take care that the antennas are (as much
as possible) unobstructed !
Avoid every limitation of the transmission
and reception area by buildings or walls
directly at or in immediate surrounding of
the antenna.
Please make sure that, especially in a
mobile production, the antennas are able to
transmit and receive in all directions freely.

2. Before operation
» Pay attention to the polarization of the
antennas.
Omnidirectional antennas normally are used
in vertical operation. Transmission and
reception antennas always have to be
aligned identically!
Exception:
fast-moving camera work, for example in
operations with steadycam etc.
Possible antenna configuration at the
receiver:
antenna 1 vertical (90°),
antenna 2 horizontal (0°)
or
antenna 1 turned to 45°
antenna 2 turned to 135°
» Installation of antennas
(by grip, universal clamps etc.)
The grip is to be attached exclusively at the
lowest end of the antenna (maximum 4cm
from the lowest end), else the properties of
the antenna will be negatively affected.

2.3. Alignment and positioning of the antennas
» Are the antennas put at a distance from the system via cables ?
Please do pay attention to the length of the antenna cable. Just exclusively use the cable
"AirCell 7" (3m, TNC male / TNC female, Art.No.: 752010006), which is available as an accessory!
Please pay special attention to the quality of the cable and plugs used!
Example: DX-cable Aircell 7
Cable attenuation: . @2,4GHz: 0,36dB per metre
@5,8GHz: 0,65dB per metre
Effect on the range: at 3dB attenuation: range divided by 1,5
at 6dB attenuation: range divided by 2
at 12dB attenuation: range divided by 4
Calculation example: if you remote the antennas at a 5,8GHz-receiver with a 10m long
antenna cable from the system, the attenuation due to the cable will be 6,5dB.
If the range without antenna cable was 2000m, then the range will reduce to 1000m
because of the antenna cable (range 2000m divided by 2).

3. SDI IN
Via a BNC connector an SDI video signal (HD/SD-SDI) is fed to to the transmitter, which is then
wirelessly transmitted to the appropiate digital video receivers.
Connector: BNC, female, 75 ohms
Standard: ANSI / SMPTE 292M, SMPTE 259M
SDI signal level: 800mV (p-p) nominal ±10%
If the transmitter does not auto-detect a new video format after this has been changed,
please restart the transmitter.
If a video signal contains a lot of noise this produces huge data rates in the encoder. In
cases of extreme noise levels in the original video signal, the resulting data rate can
increase to such an amount that the remaining available data is insufficient to guarantee
a technically proper transmission of the image.
4. SDI OUT
The SDI signal (HD/SD-SDI, embedded Audio), which has been fed in via the video input, is
displayed here.

4.1. Starting the transmitter
When the transmitter is switched on it starts with an initialisation which automatically identifies the
video norm of the input signal. The whole process takes no longer than 6 seconds.
As soon as the initialisation is finished the display should look like the above picture.
After the start-up it takes a total of approximately 30 seconds until a solid connection between
transmitter and receiver has been established. During this start-up process, occasional picture
flickering or frame drops are possible.
If the transmitter does not auto-detect a new video format after this has been changed,
please restart the transmitter.
After switching off the transmitter, the last selected program will be saved and is displayed at the
next start.
4.2. The screen saver
To save the display while operating the screen saver will be activated 30 seconds after the last
key operation. While the screen saver is activated the displayed items rolls across the screen.
The screen saver can be stopped by pressing of any key.
