Transmitter Antenna Connection:
At the transmitter’s antenna connection (SMA-female) on the right bottom of the transmitter
weatherproof housing the best emission and hence optimal coverage is achieved, if the omni-directional
antenna is at least 20 cm away from any other objects.
The transmitter may only be operated with a connected antenna. As standard the omni-directional
antenna (50 Ohm, 0 dB) will be used.
Sun Shielding:
In case of permanent solar radiation the casing should not exceed impact of + 50 ° C.
In case of higher temperatures, you must install a sun reflector or a sunroof above the
weatherproof casing
.
Transmitter Antennas:
The omni-directional antenna directly mounts to the SMA-female connector of the transmitter and
extends externally via the cable-gland directly below into an externally extending plastic tube. Refer
photo.

Planar Antenna
If the transmitter is to be operated using a directional antenna, the use of the
planar antenna ANPLA/14/5802 is permissible, with cable ANKA/0.5/SMA and the use of DG/10/5802
10dB attenuator is mandatory. The attenuator DG/10/5802 has to be installed at the transmitter’s antenna
connector (to be soldered to the antenna cable), to ensure the maximum 25mW EIRP radiated power is
not exceeded. Refer above photo.
The above-mentioned planar antenna has a horizontal beam width of 40°. To warrant an optimal range
the antenna has to be directed exactly at the receiver antenna. The antenna is vertically orientated, - the
SMA connector must point downwards. Transmitter and receiver have to have the same polarization at
all times.
Receiver Antennas:
Apart from using omni-directional and planar antennas, the receiver can also be operated using a 60cm
dish antenna with 7° beam width. On the upper side of the antenna of the parabolic mirror (PVC pipe in
the centre of the antenna) are two arrows with the labeling “vertical polarisation” and “horizontal
polarization”. The corresponding polarisation is correct if the corresponding arrow is in upward
