Diversity, Antenna Positioning and Use of Down Converters
Note: Domo down converters can be damaged by static electricity discharge when
connecting antennas. It is suggested that only antennas with built in DC path to ground
are employed to avoid static damage. If this can not be achieved then antennas should be
shorted to ground before connection to the down converter.
The domo SOLO2/SOLO4 receiver is a diversity receiver and will give
optimum results only when two antennas are deployed. The down-
converter boxes should be connected to the receiver, by connecting the
3m TNC cables supplied between the down converter connector
labelled ‘RX / IF OUT’ and the receiver connector labeled ‘IF IN’. Care
should be taken not to over tighten the TNC connectors.
The down-converters convert the RF signal down from microwave
frequencies to the UHF band, which allows the signals to be run along
longer cables without degradation. In the case of the standard domo
SOLO receiver 3 metre long cables are provided, allowing the down-
converters to be positioned remotely from the receiver.
It is important that the down-converter be positioned very close to the
antenna - long cables should not be used between the antenna and the
down converter because this can degrade system performance.
Typically antennas and down converters will be positioned outside,
usually on the roof of a building or a vehicle. The down-converters can
be located outside, because they are weather proof. However the
receiver is not weather proof and the 3 metre cables should be used to
allow the receiver to be positioned in an equipment room, rack or
housing.
The domo SOLO2/SOLO4 receiver uses an advanced diversity
technique called maximum ratio combining to construct a good
spectrum from two potentially damaged received signals. To get the
best results from diversity, the antennas should be physically separated
by at least 100cm.
Sometimes better results can be achieved by separating the antennas
further, or by positioning them of different corners of a building. The
optimum antenna placement depends on the environment in which the
equipment is used and the signal path, and is often limited by physical
factors (accessibility for example).
The domo SOLO2/SOLO4 receiver is supplied without antennas since
the optimum choice of antenna will depend on the operational scenario.
For short range or mobile applications, omni directional antennas such
as ANT4L, ANT6C or ANT4S will be most suitable whereas for longer
range fixed links, or where mobile transmit activity is happening in a
defined 120 degree arc the higher gain ANT12L or ANT12S will be
more suitable.
Antennas should be screwed directly to the TNC input of the down
converter labeled ‘ANT/RF IN’.
Video Output Connection
Connect the video output lead to the BNC connector labeled ‘VIDEO’ on
the SOLO receiver and to the chosen video display device.
