Satellite / Transponder Lists Explained

Satellite / Transponder Lists Explained

Using our lists? This is what you get.

Download the current zip compressed file and extract it. Starting in May of 2022 there may be several lists.

List start with the year and month. So this months 2205-list.zip is May of 2022. Next month will be 2206-lists.zip (June of 2022). If we do a middle of the month release, as we often do, -2 will be added, as in 2205-2-lists.zip.

2205-lists.zip will extract:

  • 2205ALL-list.pdf & 2205ALL-list.epub
  • 2205C-list.pdf & 2205C-list.epub
  • 2205DVBS-list.pdf & 2205DVBS-list.epub
  • 2205KU-list.pdf & 2205KU-list.epub

Lists Explained:

  • 2205ALL is all the satellites C, Ku, Ka. You probably don't need Ka since most meters, LNBs and receivers won't process Ka. If you install for all bands or C-band and Ku-band, this is the list for you. This list has all known satellites and all the known transponders both active and inactive.
  • 2205C is C-band only for you great "big ugly dish" diehards. This list has all known satellites and all known transponders both active and inactive.
  • 2205KU is Ku-band only for most users and installers. If you are installing a Ku dish you won't need C-band in your reference list. This list has all known satellites and all known transponders both active and inactive.
  • 2205DVBS is DVB-S only for installers who have older meters that won't process or read DVB-S2. If you align a dish to a DVB-S transponder it will be correctly aligned for all transponders. This list has all known satellites and all known transponders both active and inactive. Unfortunately some satellites no longer have DVB-S transponders. The DVB-S transponders are changing to DVB-S2 fairly quickly. If you are using a older meter this is a good time to consider upgrading to a DVB-S2 meter.

These lists include all known transponders, active and inactive. Note that not all transponders are active.

TP: is Transponder Frequency

  • C-band: 4 digits
  • Ku-band: 5 digits

SR: is Symbol Rate

Polarity:

  • Vertical or 13 for linear, RH or 13 for circular
  • Horizontal or 18 for linear, LH or 18 for circular

LO: is Local Oscillator. It is the oscillator used by your LNB or LNBF. It MUST match in your meter, so enter the same LO information from your LNB into your meter in the 'LO' field. Most LNBs have the LO printed on the label.
Common LO's are:

  • Universal Ku LNB/F: 09750 & 10600
  • US Ku LNB/F: 10750
  • DSS LNBF: 11250
  • C-band LNB/F: 5150
LNBFs with 2 LOs use 22 KHz to switch between them.
22KHz is used to switch between LOs on 2 LO (universal) LNBFs. Take a look at any spec sheet and it should tell you the LO frequencies and the output frequency. For example see the spec sheet on the famous Avenger PLL321S-2 LNBF. You will see the low band LO is 9.75 GHz and it covers 10.7 to 11.7 GHz. The high band LO is 10.6 GHz and it covers 11.7 to 12.75 GHz. So, the transponder frequency you are looking for determines which LO you should use.

  • When the 22KHz is OFF and selecting the low band frequency, 10.7 to 11.7 GHz (10700 to 11700 Mhz).
  • When the 22KHz is ON it is selecting the high band frequency, 11.7 to 12.75 GHz (11700 to 12750 MHz).

In the USA the common frequency range is 11.7 to 12.2 GHz. If you are using a universal LNBF, set the LO to 10600 and the 22KHz to ON.

  • 22KHz OFF selects LO 09750.
  • 22KHz ON selects LO 10600.

Note:
Our lists are free to download and free to use. We do not charge for our lists.
