Technician class hams are ... able to communicate through ham radio communications satellites. Most ham radio satellites make some use of the two-meter band, either for ground-to-satellite (uplink) or satellite-to-ground (downlink) signals. Many hams have contacted over 100 different countries via communications satellites. Equipment and antennas for satellite communications can be very modest; satellite antennas for two-meters are similar in size to outdoor TV/FM antennas.
