Types of Antenna some respects can be likened to an optical telescopes lens or mirror, as the antenna collects the radio signals and brings them to a focus at the dipole of the antenna. This signal is then passed along the feed cable to a receiver and amplified.

The Stanford Solar Center’s SuperSID Monitordo not have much space, as the antenna needed for the SuperSID monitor doesn’t need to be placed high up. No antenna mast is needed, and the antenna will work perfectly well at ground level, either indoors or outdoors. In fact, the indoor antenna can work very well.

Radar Detection of Meteors and the International Space Stationg. These small particles are drawn towards the inner Solar System by the Sun’s gravity and can get trapped within the debris left by comets. Together, this debris and particles are known as . and have been floating in space for many years. They are gravitationally attracted to each other and build up to form dense regions.
