SpletThe side arm is long - Reduce the ratio. Example: guestimate 0.58 ratio. Recalculate: 2.857 * 0.58 = 1.657m and adjust both arms. * If the impedance of a center-fed dipole is around 30, 35 or 40 Ohms, this table provides a estimate of the Off-Center-Feed ratio that will give approximately 50 Ohms. 40 Ohms.
SpletAn Off-Center-Fed (OCF) dipole with total span of 84+17=101 ft, with the feed point at 1/6th of the total span (101 / 6 ≈ 17 ft = 17%) from one end ( = 83 / 17 OCF). The dipole can be straight or bent. The next figure shows a variation on the original W3EDP, by adding a variable series-capacitor to the transmitter side of the transformer: SpletAn OCF at its fundamental frequency performs similarly to a center-fed dipole of the same length.
