Ku-Band Satellite (12–18 GHz)

Direct broadcast satellite TV (DBS) · VSATs · Satellite internet (HughesNet, Viasat)

Frequency Range12–18 GHz
Wavelength1.7–2.5 cm
ITU / Standard—

Applications

  • →Direct broadcast satellite TV (DBS)
  • →VSATs
  • →Satellite internet (HughesNet, Viasat)
  • →Starlink (downlink)
  • →News gathering uplinks

Propagation Characteristics

Rain fade is significant above 10 GHz. Link budget must include rain margin (3–10 dB typical). Small dish antennas (45–90 cm) feasible.

Regulatory Notes

ITU coordination required. DBS: 12.2–12.7 GHz (NA), 11.7–12.5 GHz (EU). FSS uplink: 14–14.5 GHz. Geostationary orbit coordination at 2° arc spacing.
