Recommendations for Installing DTV-TX02-DVB-S – Large
System With Quattro LNB
It is recommended that all installations of the DTV-TX02-DVB-S use an appropriately sized satellite dish
fitted with a Quattro LNB.
It is also recommended that each DTV-TX02-DVB-S unit is typically ‘tied’ to a specific LNB output, hence is
tuned to a specific frequency/polarization during initial installation only. The DTV-TX02-DVB-S receiver
does not provide LNB power and 22kHz tone, which is not required for Quattro LNB installation, providing
multiswitchers are not utilized, and each tuner is tuned to a specific range of channels available to an LNB and
not re-tuned regularly.
FIG. 97 shows a typical recommended installation for the AMX DVB-S receiver. Various options are
available, including alternative manufacturers for the satellite amplifier, and the active splitters shown could be
replaced by passive alternatives if the number of receivers is small and the associated signal lose is acceptable.
The splitters could also be replaced by any suitable distribution amp, providing they are suitable for the
frequency range 950-2150Mhz and do not present multiswitch outputs. Suitable distribution amplifiers are
available from Proception – Starbox proSTR5S, porSTR10S, or Labgear HDU681S, HDU641S.
