Collinear Dipole Antenna Calculator. The collinear dipole, unlike the coaxial dipole requires a ground-plane to operate. A dual element collinear dipole gave me the same results as an eight element coax collinear. Although this design is not ideal for a 'pipe antenna' it is ideal for mounting in any antenna mast.The folded dipole, short dipole, cage dipole, bow-tie, and batwing antenna are the different variations of the dipole used. Use this online dipole antenna calculator to calculate the dipole current (I), electric wave (E θ), magnetic wave (H Φ) and average radiated power density (P d).This calculator can be used to design a Slim Jim or a J Pole antenna. The Slim Jim, designed by the late Fred Judd, G2BCX, can be a great portable 'roll up' antenna, if made out of 300Ω or 450Ω ladder line / twin feeder. Add a loop of string to the top, and hang it on a tree branch, use it with your handheld transceiver, then roll it up and ...Figure 5.32 A dipole in an external electric field. (a) The net force on the dipole is zero, but the net torque is not. As a result, the dipole rotates, becoming aligned with the external field. (b) The dipole moment is a convenient way to characterize this effect. The d → d → points in the same direction as p → p →.Calculate the dimensions and feedline of a simple dipole antenna for amateur radio bands.

Antenna gain is a critical concept in wireless communication. Represented by 'G', it measures the efficiency of an antenna to direct energy in a specific ...An electric dipole is defined as a couple of opposite charges “q” and “–q” separated by a distance “d”. By default, the direction of electric dipoles in space is always from negative charge “-q” to positive charge “q”. The midpoint “q” and “–q” is called the centre of the dipole. The simplest example of an ... ….

Some manufacturers specify the gain of their antennas relative to that of a half wave dipole. It’s important to check the specifications and units in the data sheet to confirm. A dipole does not have to be half wavelength long. It can be λ, 5λ/4, 3λ/2. Use the dipole antenna calculator to find the physical dimensions. Related CalculatorsThe overall dipole moment of a molecule depends on the individual bond dipole moments and how they are arranged. (a) Each CO CO bond has a bond dipole moment, but they point in opposite directions so that the net CO2 CO 2 molecule is nonpolar. (b) In contrast, water is polar because the OH bond moments do not cancel out.

If you are interested in how to build a copper J-pole antenna, follow these instructions: Choose 145 MHz from the 2-meter frequency band, note the speed of light c, and calculate the wavelength λ from the formula λ = c/f = (299,792,458 m/s) / (145,000,000 1/s) = 2.07 m. Check the velocity factor for bare copper, which is 0.96.Dipole online calculator. As is known, the length of a half-wave dipole is equal to half the wavelength in free space, but taking into account the shortening factor. The shortening factor K, in turn, depends on the ratio of the wavelength to the dipole diameter. This dependence is usually given in the form of a graph:When determining how long to make each leg of a Dipole antenna, dividing the frequency in MHz into 468 will give the overall length. To find the half wave, divide that number by two. This will give you the length of each leg of the antenna. Example — 80 meters: If you are operating on 3.8 MHz, dividing 3.8 into 468 gives 123.16 feet over all.

www menti com 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.Antenna Calculator.
