85cm, 1.2m or 1.8m offset dish and LNB

  • High-quality powder-coated aluminium (85cm, 1.2m) or glass-fibre reinforced compression moulded polyester (1.8m) reflector.
  • 2.4–3.7m antennas also available for fringe area reception.
  • Supplied with azimuth/elevation mounting bracket (85cm, 1.2m), 50m of CT100 75Ω co-axial cable and F-type connectors.
  • 1.8m antenna supplied with 4” tubular pedestal (optional non-penetrating roof mount also available).
  • State-of-the-art weatherproof LNB with a noise figure of 0.3dB.

DVB receiver and software

  • Ayecka SR1 (desk or 19” rack mount) or TBS 6903 (PCIe card) DVB-S2 receiver, both recommended by EUMETSAT.
  • The TBS 6903 receiver allows both EUMETCast transponders (basic/HVS1 and HVS2) to be received simultaneously with a single antenna. The HVS2 transponder includes GOES-16 ABI level 1b data which has replaced GOES East images previously transmitted on the EUMETCast LRIT service.
  • Supplied with drivers and T-Systems Business TV-IP software.
