What antennas have you built so far? How large do you want to build this dish? What are you going to use for your LNA and receiver stages? How will you be analyzing the data? Will this dish be movable, or will it be anchored to the ground?king yasin ally said:I am trying to build my own communication / listening dish, multi frequency antenna, basically my own deep space antenna network. how to get the needed supply for such endeavour? help with any info on this,
a new field for me.
thanks!

cheersA Deep Space antenna, also known as a dish antenna, is a large, parabolic-shaped antenna used for communicating with spacecraft and probes that are exploring deep space, beyond Earth's orbit. It is designed to receive and transmit signals over long distances and at high data rates.
A Deep Space antenna works by reflecting and focusing radio waves off its curved surface towards a specific point in space. This point is where the spacecraft or probe is located. The antenna receives the weak signals from the spacecraft and amplifies them to be processed by ground stations on Earth, and vice versa for transmissions.
Deep Space antennas can vary in size, but they are usually very large, ranging from 20 to 70 meters in diameter. The larger the antenna, the more sensitive it is to weak signals from distant spacecraft. Some antennas, such as the Deep Space Network's 70-meter antennas, are among the largest movable structures on Earth.
Deep Space antennas are strategically located around the world to provide constant communication coverage with spacecraft, no matter where they are in space. The most well-known Deep Space antenna network is the Deep Space Network, which has three main locations in California, Spain, and Australia.
Deep Space antennas are designed to receive a wide range of signals from spacecraft, including radio waves, X-rays, and other types of electromagnetic radiation. These antennas can also receive data signals from spacecraft, such as images and other scientific data, for processing and analysis on Earth.
