Parabolic dish is widely used as satellite tv channel receiver across the world.
Satellite antenna gain calculator.
Figure of merit calculator.
Lambda the wavelength of the antenna in meters.
Satellite system calculator for modern electronic communication 9 e jeffrey s.
D the diameter of the dish.
Antenna gain is the measure of amount of boost provided to the input sigal by the antenna.
Gain 52 3 db beamwidth 0 35 degrees aperture 5 77 meter 2 parabolic antenna calculator equation.
It is the power supplied to an antenna multiplied by the antenna gain in a given.
The uplink antenna gain is easy to calculate.
The antenna gain shown in top line of the results is the on axis gain.
Antenna gain dbi beamwidth aperture efficiency calculator.
The above formula is to calculate the gain of a parabolic dish antenna where.
There are two calculators here so you can compare the results against each other.
Beasley and gary m.
The gain of an antenna dbi in a given direction is the amount of energy radiated in that direction compared to the energy an isotropic antenna would radiate in the same direction when driven with the same input power.
K the efficiency fo the antenna.
Maximum main beam gain.
Antenna efficiency 0 7 antenna diameter 4 2 meter antenna frequency 6 ghz output gain dbi 47.
This calculator is considering only power and antenna gain.
Simply enter the efficiency wave length physical aperture area to calculate the gain or frequency of antennas.
Antenna gain calculator equation.
Frequency 14 5 ghz diameter 3 5 meter outputs.
Then enter the antenna gain.
Distance to from and round trip time delay calculator.
The results are increasingly approximate beyond the 3 db contour.
Azimuth and elevation calculator.
Antenna gain calculator example.
This analysis does not accomodate for power or gain in the system which you can easily overcome with antenna and rf amplifier size.
By definition erp is the abbreviation for effective radiated power that is directed in a given direction.
Dbi means relative to an isotropic omni directional antenna.
Finally click on the calculate button for the pure erp and eirp.
This has been calculated based on the frequency entered frequency to wavelength calculator.
The uplink system noise temperature is obviously related to the quality of the receive low noise input amplifier on the satellite waveguides.
