WebFor a "typical" parabolic antenna k = 70 when θ is in degrees. For a typical 2 meter satellite dish operating on C band (4 GHz), like the one shown here, this formula gives a beamwidth of about 2.6°. For the Arecibo antenna at 2.4 GHz the beamwidth is 0.028°. It can be seen that parabolic antennas can produce very narrow beams, and aiming ...
