Amateur radio satellite antenna

Line of sight of Radiosonde does not kick in till it is about ft ascending and max I can decode so far is about miles from my Locationwhich is when Radiosonde deflates. One of the associated phenomena are reflections at Aurora zones which can influence the propagation of radio waves and provide DX conditions. Since January I am part of the ground station network which receives the signal and streams it via the internet to a central server in UK where it is combined and made available for all interested people see the link to the right. Documentation is also available by Product. Qatar Oscar — QO EUR ,75 Compralo Subito 24d 12h.

A number of them are still usable, some even multiple times a day. The satellite dish antenna is two basic parts, the parabolic reflector and the feed at the focal point of the parabola. This is done to achieve isolation between the signals, as is done on earth by separating a repeater's receive and transmit frequencies.

Contact Us. A number of Radio Amateur satellites have been launched, operated, and reached end of life. In other, lower frequency bands, it is normal to make many contacts in various places with a low-gain more omnidirectional antenna that does not have to be re-aimed as much or at all. There are articles explaining how to convert a satellite TV antenna to a stealth 2m Mhz slot antenna, such as here and here. A store-and-forward configuration offers the perhaps multiple retransmission of the data either for a number of times, at a certain time, or when the satellites approximate position reaches a certain area or range.
