That dish looks exactly (except for the LNB) like the PanSat dish I use for DTH packages on Intelsat Americas 5 (formerly Telstar 5).
The bigger dish will probably be a much needed help for those in the West, but with look angles at 40 and above in the East it might not make much of a difference. Signal here with an 18" dish during overcast skies is 95, and 97 with clear skies. Although it hasn't rained with VOOM yet, when I had E* there could be monsoon rains with 119 & 110 going out, but 61.5 never lost a signal.
Judging by the pictures it doesn't appear this dish is readily able for multi-sat use. There's doesn't seem to be a skew setting nor anywhere to place an additional LNB.
Thanks for sharing the pics.
