What is the satellite name and orbit location ?
Orbit inclination ?
What is the exact frequency range ?
What is the type of polarisation - linear or circular ?
Is operation co-pol or cross-pol ?
What is the uplink beam coverage map ?
What is the downlink beam coverage map ?
What is the price per MHz per month ?
Is this backed up or premptible capacity ?

Please provide the operating EIRP per MHz. �I don't believe your 44.6 dBW for 14 MHz.

Please say if you already have a contract in place with the satellite operator and if so the contact name at the satellite organisation, so that this may be verified. �Sorry to be fussy but clarity helps avoid misunderstandings and mistakes about who exactly has leased what exactly as I am anxious to avoid situations where the same capacity appears to be for sale from multiple vendors !

Best regards, Eric.

What is the satellite name and orbit location ? Arabsat 2B
Orbit inclination ? 0
What is the exact frequency range ? Europe, east to Afghanistan, down to Nigeria and Kenya.
What is the type of polarisation - linear or circular ? Circular.
Is operation co-pol or cross-pol ? Regular C band, not extended.
What is the uplink beam coverage map ? HEMI
What is the downlink beam coverage map ? Same.
What is the price per MHz per month ? US$4,800 (Optional Uplink US$480/M) Pricing only applicable to this particular deal with special term of initial 90 days followed by mutual monthly term agreement.
Is this backed up or premptible capacity ? Non-preemptible. See term.

Please provide the operating EIRP per MHz. �I don't believe your 44.6 dBW for 14 MHz. (Please see map. It is 44.6 dBW for the coverage with outer bands between 41 and 40 dBW outside specified regions).

Longterm agreements in place. https://www.emc-corp.net/emc-news2_not17.htm

Hope this helps. If any further questions, please let me know.

Thanks,

Camilo

Here are the downlink and uplink coverage maps for the high power C band transponders on Arabsat 2B at 30.5 east:

Arabsat 2B 30.5E C band High power downlink coverage map.

Arabsat 2B 30.5E C band uplink coverage map.

The Arabsat 2B technical manual is here:
https://link.arabsat.com/pr/PDF/ARABSAT2BTUG.PDF (1.2 Mbytes pdf file)

Any students or engineers interested in doing link budget calculation should download this document as it is particularly clear about the satellite parameters.

When operated in multicarrier mode the output back off for C band transponders is about 3.1 dB. �So take this off the full transponder EIRP and then subtract a further 10log(14/36) dB to get the share of the available operating downlink EIRP for the 14 MHz lease bandwidth out of the full 36 MHz transponder bandwidth. Then take off 10log(1/14) dB to get the dBW per MHz.

Contact Camilo cgarcia@emc-corp.net +1.305.924.4462 if interested in leasing.

Best regards, Eric.
