What is the frequency range of a six foot dish antenna?

The size of the dish isn't as important as the length of the antenna. The antenna is INSIDE the little can at the focus of the dish. The length of the antenna is tuned to the wavelength of the frequency being received.


What is the formula to calculate the power radiated by antenna?

The power radiated by an antenna can be calculated using the formula: [ P_r = \frac{P_t G}{4\pi d^2} ] where ( P_r ) is the radiated power, ( P_t ) is the total power input to the antenna, ( G ) is the gain of the antenna (dimensionless), and ( d ) is the distance from the antenna to the point where the power is being measured. This formula assumes free space conditions and isotropic radiation.


What is antenna center line?

The antenna center line refers to an imaginary vertical line that represents the midpoint of an antenna's height, extending both above and below the antenna structure. It is crucial for determining the antenna's radiation pattern and effective height in relation to ground level, affecting its performance and coverage area. Engineers use this reference to ensure proper alignment and orientation during installation to optimize signal transmission and reception.


Why is a antenna a square base pyramid?

It can be but need not be.


What are the common shapes for antenna reflectors?

A lot of parabolic reflectors are used in antennas, particularly with frequencies in the microwave region. There are a few other shapes, but they are infrequent choices for antenna designers.
