Dipole calculator.

To find the electric field at a point due to a point charge, proceed as follows: Divide the magnitude of the charge by the square of the distance of the charge from the point. Multiply the value from step 1 with Coulomb's constant, i.e., 8.9876 × 10⁹ N·m²/C². You will get the electric field at a point due to a single-point charge.When determining how long to make each leg of a Dipole antenna, dividing the frequency in MHz into 468 will give the overall length.
