Nov 22, 2012 · A ½-wave dipole is one type of antenna that does not require a ground plane. Most dipoles are center fed, which means that the transmission line is connected at the center of the dipole. Keep in mind that we want the antenna to be vertically polarized so that means that our dipole should be vertically oriented.

Much more commonly, this unit is expressed in Ampere square meters, A m 2. Electrical engineers and physicists find this useful. It's an easy conversion: 1 A m 2 = 1 N m / T. You can calculate the dipole moments value yourself using the formula shown here. Or use our online Pull Force Calculator, which calculates the dipole moment.

The second example is fairly easily rectified by simple adding or subtracting some length to either the dipole or the feed line, often as little as a metre will do the trick. While the antenna is well less than a half wave length at 1.8 MHz, at just over a quarter wave length it will still give usable access to this band.
