Ku LNBF: Standard or Universal ?
Jack Wang
asked to enter LNBF type. My old LNBF was for a analog receiver and I felt
it must be a standard type. Any one help me to understand the difference ?
Will that old LNBF be compatible with my new digital receiver (it was
labeled as a 'digital LNBF'),,,
Thanks,
Jack

Setting up an MPEG2 Receiver - Frequencies
Installing an MPEG2 receiver is different from installing the old analog
receivers.
In the MPEG2 receiver is a listing of each satellite's frequencies.
Each satellite has many different "transponders" which send out different
frequencies. And each frequency can have many different TV/radio channels
broadcast on it.
The MPEG2 receiver also has a listing of frequencies for each satellite. A
new MPEG2 receiver may not have an updated list of frequencies for each
satellite or may have only one or two frequencies listed for each
satellite. So once the MPEG2 receiver is connected to the dish and the dish
is aligned properly, you will need to enter transponder frequencies for
each satellite before you can receive any channels.
The frequencies for each satellite are listed at lyngsat.com and
satcodx.com.
C band frequencies are from 3.4 GHz to 4.2 GHz and Ku frequencies are from
10.7 GHz to 12.75 GHz. So the frequencies listed on lyngsat.com which are
the 3's and 4's are for C band. The frequencies listed in the 10's, 11's,
and 12's are for Ku band. Not all C band LNB's or Ku LNB's will receive all
these frequencies...
Regular C band LNB = 3.7 GHz to 4.2 GHz
"extended" C band LNB = 3.4 GHz to 4.2 GHz
Standard Ku band LNB = 11.7 GHz to 12.2 GHz
"Wideband" or "universal" Ku LNB = 10.7 GHz to 12.75 GHz
If you have a big dish, you will need a "wideband" feedhorn before you can
use the wideband LNBs. Needless to say. If you only have a regular C band
LNB with a regular feed horn, entering in transponders with frequencies
such as 3.4 Ghz or 10's, 11's, or 12's will not work. So if you have a
regular C band LNB only, only enter frequencies in the 3.7 GHz to 4.2 GHz
range. Don't waste your time entering frequencies which you will not be
able to receive.
To enter frequencies on my Satcruiser DSR 2040, I press Menu, Installation,
Tp configuration.
Scroll to LNB, press OK.
Scroll to LNB Type, then use left right arrows to select standard or
universal LNB. Then scroll to LO Freq. and enter the "local" frequency of
the LNB. For a C band satellite "frequency listing" 5150, for Ku band
satellite "frequency listing" 10750. If a Ku universal LNB, then usually...
LO 10600 and LO low 9750.
-or-
LO 10750 and LO low 9750.
Press menu to get back to Tp configuration.
Scroll down to the frequencies listed.
Review the current frequencies on lyngsat.com with those frequencies
listed. Delete outdated frequencies by highlighting the frequency and
pressing clear.
To enter new frequencies, scroll to add. Then press OK.
Scroll to Frequency, then press OK. Then enter the number of the new
frequency. Don't forget to press 0 first if only a 4 digit C band
frequency. (Can press OK to exit from change number mode if cursor remains
after entering new number.)
Scroll to Polarization. Use right left arrows to select Ver or Hor.
Scroll to Symbol Rate. Click OK to change number. Enter symbol rate for
that frequency. (If there is no symbol rate listed for the frequency, the
frequency may be a NTSC or an analog channel. This will not work for MPEG2
digital, so enter another frequency which has a symbol rate listed.)
Press menu to return to TP configuration.
Continue to add all appropriate frequencies from lyngsat.com or
satcodx.com.
Setting dish position on positioner model receiver...
When finished adding frequencies, scroll to the first frequency in the
frequency list. Click OK. Scroll to position. Use the left right arrow to
move your dish back and forth. As you move the dish, watch the signal meter
at the bottom of the screen. When you hit a satellite, the signal meter may
show some activity.
Now this part is tricky. You need to be sure you are pointed at the
*correct* satellite! You could be on the wrong satellite. The best method
is to use the dish pointing calculator below and a handheld GPS to verify
that the dish is pointed at the correct satellite. Walk outside with the
GPS and walk away from the dish in the direction it is pointing. This will
give you a heading in degrees. Compare that with the dish pointing
calculator azimuth for that particular satellite. If the calculator says
180 degrees and the dish is pointing 100 degrees, you are pointing at the
wrong satellite. Note that some GPS have a magnetic and actual heading. Use
the actual heading and not magnetic.
If you get no activity on the signal meter by moving the dish back and
forth, press menu, select the second frequency, and try again. Some
frequencies have nothing on them. Now usually frequencies which have a lot
of "free" (F) channels listed on lyngsat.com will get all sorts of activity
on the signal meters when you pass by the satellite. With my receiver, I
get orange bars showing up on the signal meter if it is an active
frequency. These are the frequencies which will usually have channels on
them.
Once you find the satellite, use the left right arrows to get the highest
"S" reading. May need to go one click at a time in either direction to see
where the best signal is. If I am getting 50's and 60's readings as I
position around the satellite, I will move toward the satellite until I get
the first 60's reading. Then I count and I move one click at a time. Say I
move 12 clicks and it remains in the 60's. Then on the 13th click, it goes
back to the 50's. I will then move back half way or 6 clicks so the dish is
centered within the 60's range. Sometimes you can just move it back and
forth and a particular spot has the highest reading.
After you find the best spot to position the dish for that satellite, press
OK and the receiver will mark that spot for that satellite.
Next press menu to go back to TP configuration. Scroll to search for
channels and press OK.
The receiver will now search each frequency for channels and add them to
the channel guide. Go back to the first menu when the search is done and
press TV Channels. Then select a channel and watch TV. Use the left arrow
in this menu to select the satellite or all satellites.
Note: Some satellites have nothing on them. So you can enter 15 different
frequencies, find the satellite, search for channels, then get nothing.
Other times you could be pointed at the wrong satellite. So try moving to
another position which gets a signal reading and search again.
Telstar 5 has a lot of free channels, so may want to start with that
satellite for learning how to do this. Links follow...

are only interested in a specific
channel requiring a Universal, the vast majority of available channels use
Standard LNBFs.

As far as the LNB line, they are all block.
