22kHz Switchbox is an electronic switch which is controlled with a 22kHz
signal from the satellite receiver. The switch can be found between the
receivers and the satellite equipment. Attention! When this point is not
properly configured, it could happen that only one satellite will be found in a
search (usually the satellite which is connected to the first port (0kHz) of the
switchbox).
Multiswitch
Multiswitch is usually applied in order to distribute one or more satellite
signals to many satellite ports in one house.
The main task is the distribution of signals delivered byLNB to individual
satellite receivers. Moreover, its purpose (depeding on the design) is the
feeding of terrestrial or cable tv signals into antenna lines to participants.
Repetition rate (in DiSEqC operation)
The repetition rate shows how often the digital command from the satellite
receiver should be transmitted to multiswitch. Usually here the choice „0 –
repetitions“ can be retained. However, if there is a problem with the
actuation of the equipment, try repetition rate "1" or "2".
Community installation (single cable system)
is a type of antenna system arrangement in which through abandoning direct
current-remote power supply 14/18 Volt and DiSEqC-control signals a high-
frequency signal in frequency range 950 – 2250 MHz (satellite range) can be
linearly delivered to many participants of a community radio reception system.
In this case it is possible to distinguish between simple single cable solutions
and programmable single cable solutions. Currently SHARP LCD-TV supports
only the simple solution.
Simple single-cable systems can be often found in older community facilities
and most often don't transmit digital channels but only analogue ones.
Astra 1 / Astra 2 / Astra 3
In the installation menu of LCD-TV you can choose from various Astra
satellites.
