It has considered for each band the uplink and downlink frequencies, including the frequency bands 25 MHz. A report from Euroconsult has explored the current and future supply and use of the extended C-Band, the planned C-Band and the 7025-7075 Mhz Band for satellite services. Now, there are dozens of amateur radio satellites in space, and as a Technician you can make contacts by bouncing your signals off of them. In Europe, Ku-band downlink is used from 10.7 GHz to 12.75 GHz for direct broadcast satellite services, such as Astra. Study: C-band usage by satellite networks. ![]() In single band mode the antenna operates at the uplink C-band (5.9 to 6.7 GHz) of satellite communication and in dual band mode it operates at both the downlink (3.4 to 4.2 GHz) and uplink (5.9 to 6. The antenna can be switched into two operating modes electrically. It only lasted a few weeks before it dropped into Earth’s atmosphere and burned up, but it secured amateur radio’s place in space. A frequency band reconfigurable wideband antenna designed for C-band satellite applications is presented. Some satellites carry transponders for both C and Ku bands. The Ka and Ku bands are reserved exclusively for satellite communication but are subject to rain attenuation. ![]() It carried a small beacon transmitter whose purpose was to study radio propagation through the ionosphere. The following table shows the main frequency bands used for satellite links. For example, one of the other cool things you can do with a Technician Class license is work the “birds,” otherwise known as amateur radio satellites.ĭid you know that amateur radio operators have been sending satellites into space since the early 1960s? The Orbiting Satellite Carrying Amateur Radio, or OSCAR I for short, was successfully launched into a low Earth orbit on December 12, 1961. This is fun for a while, but don’t get stuck just talking on the repeaters. 14.0-14.5 GHz band was allocated domestically and internationally to the LMSS on a secondary basis, and that the 11.7-12.2 GHz frequency band contained no allocation for MSS. When new hams get their licenses, they generally purchase a handheld transceiver (HT) and get on the local repeaters.
