Step 2: Check RF Head parts
LNB
The LNB provides the low noise amplification and down conversion from
Ku-band to L-Band. The down converted signals are then routed to the
RCST via coaxial cable. Based on the satellite downlink frequency bands,
the LNB is available to receive the frequencies in Megahertz.
It is required that your measurement equipment you use for calibrating
the antenna is capable of resolving the L- Band frequency, as this is the
frequency you will see on your spectrum analyzer when installing the
antenna.
There are many different LNBs available with 12,75, 10 Ghz, 11,3 Ghz
and 5,15 Ghz Oscillator frequency. So have a look on your LNB to
verify that you have the correct model in your delivery.
10 Ghz For 10.95 – 11.7 Ghz
11.3 Ghz For 12.25 – 12.75 Ghz
5.15 Ghz For 3.4 – 4.2 Ghz

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Please check that you do not have an outdated manual, as this may lead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.

A 4 Watt version is available as compact transceiver which from its
concept is superior than a separate BUC.
The 4 Watt transceivers do satisfy their power requirements due to a
higher efficiency by the RCST as well. Separate NJRC BUC do require
complex additional and fault intensive power supplies.
The NJRC transmitter is not the most modern one. Nevertheless it is
reliable also under extreme climatic conditions and our STANDARD
product. The output power is 2 Watt in this version. It is certified in most
European countries. Please keep in mind, that transmitters higher than 2
Watt are not certified in most EU countries and therefore might not be
available in your region in which you want to operate your system.
The 2 Watt STANDARD version has the following specifications:
For W6 satellite, Indian Sea Footprint a transmitter with extended
frequency range of 13.75 to 14.25 Ghz is required. This transmitter is
shipped with all systems for this satellite footprint. It also has 2 Watt
transmit power.
Please see the specifications on the next page.

We also do supply a 3 Watt BUC from NJRC. This is the NJT5037 model,
which is smaller and has a slightly higher transmit power output.
This is especially available for regions in which there is high humidity in
the air, like in some regions in Africa or in areas, where footprints
smoothly fade out on the upstream side.
Please see the specifications on the next page.

Transceiver
A Transceiver integrates Receive LNB, OMT and BUC in
one box and is therefore quite compact. It is the
modern version of the separated versions of BUC/ OMT
& LNB above. Level421 has started shipment of this
new product, so it might be that you already receive a
transceiver with your equipment shipment. A 2 Watt
and a 4 Watt Version is available. As some satellites are not yet approved
with the new transceivers, you also might have received not a transceiver
with your shipment.
In comparison to the NJRC BUC, the Skyware transceiver for safety
switches off the ODU if not on signal. So as default the ODU LED will stay
OFF. In order to activate the transceiver, please enter the save boot
parms and bring the unit pointed correclty to the satellite. Afterwards the
ODU LED should show up in green.
