Norsat LNB Type:
The frequency is depending on the satellite or the transponder you need
to adjust your antenna on. Please find in the appendix a table with an
overview on all satellite frequencies which are used by our services.
L-band Freq = Fcrt - LNB Local Oscillator frequency (in MHz)
Where: Fcrt = RF downlink frequency of known carrier, in MHz
LNB Local Oscillator Frequency varies for different bands
Please check that you do not have an outdated manual, as this may lead
you to adjust the antenna to a wrong carrier frequency. Depending on
grade of service and Hub operator, these values may change without
prior notice. It is a good idea to check these values again with us by mail
prior you start your installation.
BUC
The BUC (Block up converter) accepts transmit signals from the RCST and
provides up conversion to the satellite uplink frequency and transmits
them to the satellite.
For the TT-3XX0 ™ ODU, the BUC includes a Solid State Power Amplifier
available as Ku-Band transceivers for 2-, or 3- Watt. The RCST provides a
24VDC source to power these units. For the 4-Watt Ku-band NJRC
manufactured BUC, the RCST is equipped with an external power supply
adapter to satisfy the additional power requirement. Level421 has
decided only to supply the 2 Watt and 3 Watt version for several reasons.
