If you are designing a satellite you may estimate the uplink g t by considering the uplink antenna gain and the satellite receive system noise temperature. Parabolic antenna calculator example. Parabolic dish is widely used as satellite tv channel receiver across the world. The above formula is to calculate the gain of a parabolic dish antenna where.

Maximum main beam gain. By definition erp is the abbreviation for effective radiated power that is directed in a given direction. Simply enter the efficiency wave length physical aperture area to calculate the gain or frequency of antennas. It is very useful in rf system link budget calculation and analysis.

Azimuth and elevation calculator. D the diameter of the dish. Antenna gain calculator example. The antenna gain shown in top line of the results is the on axis gain.

K the efficiency fo the antenna. The uplink antenna gain is easy to calculate. This calculator is considering only power and antenna gain. Dbi means relative to an isotropic omni directional antenna.

It is the power supplied to an antenna multiplied by the antenna gain in a given. Antenna gain is the measure of amount of boost provided to the input sigal by the antenna. Then enter the antenna gain. Frequency 14 5 ghz diameter 3 5 meter outputs.

There are two calculators here so you can compare the results against each other. Distance to from and round trip time delay calculator. Finally click on the calculate button for the pure erp and eirp. 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.
