Question

Electronics

Is it possible to establish communication between a satellite and a ground object at a wavelength of 2000 meters? I am not an expert in radio communication, but I would like to know the answer

Answer 1

No. The ionosphere does not transmit such waves.

Answer 2

well, if the orbit is low, then one could experiment :)
though the size of the antenna :))

Answer 3

In the same place like microwave waves are used. No, the upper layers will not miss. And waves of a similar length, if my memory serves me, are used to communicate with submarines.

Answer 4

The dimensions of a more or less effective antenna will turn out to be too large, the same half-wave dipole should be 1 km long, this will have to be taken with an equivalent length using an inductance for "extension". Plus, the propagation of radio waves of this length does not pass through the dense layers of the atmosphere - they are mostly reflected .... due to many reflections from the ionosphere and the surface of the earth, and long-distance communications of the kv-sv-dv ranges are achieved. so you can't get in touch
