Es'hail-2 Basic Information
To receive Es'hail-2 at 26°E you can use standard satellite LNBs. These can also be modified. (Note there are other standards and new wideband LNBs. We are talking about traditional ones available in 2019). This is intended to be a basic guide, there are more details and information on how to modify equipment to greatly improve performance is available on this page
Aligning your dish
Update on how to align your dish
Now Oscar 100 is "on air" the advice about aligning your dish on BADR4 etc is out dated.
Use some SDR hardware (and £10 RTL dongle will do) and something like the SDRconsole or SDR# programs set for 1MHz bandwidth centered on 739 / 740MHz. Supply 12v to the LNB and look for a bump of around .5MHz bandwidth.
This is the easiest way as there are no other signals in that band, set the elevation to ~ 36 degrees and gently scan across in Azimuth until you see the bump.
You can then use the TV beacon to tweak for maximum signal - the types of MER you should receive depending on dish size are listed on the bottom of this page: https://wiki.batc.org.uk/Receiving_Oscar_100_DATV_signals
