A bowl-shaped antenna that reflects and focuses incoming ... Also called a "dish" or "mirror," parabolic antennas are used for satellite signals and planetary telescopes. The reflective mirror ...

Both cover the whole frequency range, but can be optimised for gain in certain bands by telescoping the feed horn between detented positions. Construction is aluminium rod-and-bar, with hand-welded ...

A parabolic antenna brings radio waves from a particular direction in space (along the axis of the parabola) to a focus as in Figure 1. The radio waves from the direction along the axis arrive at the ...
