The voltage and frequency delivered to a magnetic dipole ham antenna can vary widely depending on a number of factors, such as the specific type of antenna, the frequency band being used, and the power level of the transmitter.
In general, the voltage and frequency delivered to a ham antenna can be calculated using the following formulas:
V = E * (λ/2π) * (π/4)^(1/2)
f = c / λ
Where V is the voltage, E is the electric field strength in volts per meter (V/m), λ is the wavelength of the signal in meters, f is the frequency of the signal in Hertz (Hz), and c is the speed of light in meters per second.
For example, if we assume a ham radio signal at a frequency of 14.2 MHz (14,200,000 Hz) and a wavelength of 21.1 meters (the approximate wavelength for this frequency), the voltage delivered to a magnetic dipole ham antenna with an electric field strength of 1 V/m can be calculated as:
V = E * (λ/2π) * (π/4)^(1/2) V = 1 V/m * (21.1 meters/(2π)) * (π/4)^(1/2) V = 2.71 volts
Similarly, the frequency of the signal can be calculated as:
f = c / λ f = 299,792,458 m/s / 21.1 meters f = 14,200,000 Hz
It's worth noting that the voltage and frequency delivered to a ham antenna can vary widely depending on a number of factors, and these formulas provide only a rough estimate. In addition, the voltage and frequency delivered to the antenna can also depend on the impedance of the antenna, the feedline, and the transmitter.
