I'm not an expert in this area, but if I remember correctly a lot of satellites use radio links in the neighborhood of 10 Ghz for ground communication because they've found that band isn't affected much by atmospheric conditions.
- pclmulqdq 4y ago10-100 Ghz has very few bands where water is an absorber. It tends to fall between the molecular and atomic modes of many molecules, so you only suffer free space loss (which is still significant over long range at high frequency).
- walrus01 4y ago"traditional" geostationary satellites use various c, ku, ka and high ka bands. Anywhere from 6 to 30 GHz. Depends a lot on how new it is, what its intended use is and transponder/antenna configuration. and also depending on the intended size/type of earth stations and remote terminals. in addition to tracking/telemetry/control low data rate radios in the L/S-bands.
