To receive EsHailSat at 26E 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)
 
 
DC Supply
 
 
The basic LNB requires a DC supply fed up the coax. This powers the internals and also selects polarisation. A 12V supply selects Horizontal polarisation, an 18V supply Vertical polarisation. There are usually two local oscillator frequencies, 9.75 GHz and 10.6 GHz. The higher is selected by adding a 22kHz signal to the DC supply. For EsHail use the lower LO is used and this 22kHz tone is not required.
