WebEquation for calculate parabolic dish antenna beamwidth is, θ (degrees) = 70•λ / D. θ (radians) = λ / D. where, D - dish diameter, λ - wavelength, θ - antenna beamwidth. … WebThe beamwidth of a small dish is broader than the beam of a large dish, making tracking less difficult. Of course, the dish needs a feed antenna, and a short helix is a good choice for circular polarization. A small offset dish is very attractive, since the feed blockage, which degrades small dish performance, is greatly reduced.

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 ... In parabolic antennas, virtually all the power radiated is concentrated in a narrow main lobe along the antenna's axis. The residual power is radiated in sidelobes, usually much smaller, in other directions. Since the reflector aperture of parabolic antennas is much larger than the wavelength, diffraction usually causes many narrow sidelobes, so the sidelobe pattern is complex. There is also usually a backlobe, in the opposite direction to the main lobe, due to the spillover radiation f… lowes pressure treated decking wood
