Es’hail 2

Coverage area of Es'hail 2

Qatar’s Es’hail 2 satellite will provide the first amateur radio geostationary communications that could link amateurs from Brazil to Thailand. The satellite is expected to launch at the end of 2016 and will be positioned at 25.5 degrees East.

Es'hail-2 coverage areaEs’hail 2 will carry two “Phase 4” amateur radio transponders operating in the 2400 MHz and 10450 MHz bands. A 250 kHz bandwidth linear transponder intended for conventional analogue operations and an 8 MHz bandwidth transponder for experimental digital modulation schemes and DVB amateur television.

Narrowband Linear transponder
 2400.050 -  2400.300 MHz Uplink
10489.550 - 10489.800 MHz Downlink

Wideband digital transponder
 2401.500 -  2409.500 MHz Uplink
10491.000 - 10499.000 MHz Downlink
