This type of antenna is a popular antenna design as the performance is very good across the HF bands and requires little or no tuning. It’s a dipole fed off center with a 4:1 balun at the offset feed point.
The off-center-fed dipole is a versatile multiband HF antenna when properly fed. Understanding how it works can pay dividends. Here is what you need to know.
Antenna Length Calculator. 1. What type of antenna do you want to build? Dipole. Fan Dipole. Inverted Vee. Off Center Fed Dipole. Vertical. 2. What frequency will you be operating on? Frequency: MHz. Meters Feet. 3. Here's your antenna...
7 lip 2020 · The OCF or Off Center Fed Dipole antenna is much like a conventional dipole antenna in that the formula you use to calculate the length of it is the same. That is: 468 / Frequency Mhz will give you the overall length of the antenna.
18 sty 2020 · This Off Center Fed Dipole is set up for 80m. If you want a different frequency, calculate the length of a standard half wave dipole. Instead of dividing the length in half, multiply it by .64 and .36. Basically, one leg is 64% of the half wave and the other is 36%.
23 paź 2011 · Here is a spreadsheet I designed in Microsoft Excel for calculating the first cut and the final cut (after testing) of a 1/2 wave dipole, whether center-fed, classic off-center-fed, Windom, or New Carolina Windom.
5 cze 2021 · The Antenna Calculator for Half-Wave Dipoles. Enter your desired frequency (MHz) of operation (i.e. 3.55). If you have no particular preference within a given ham radio band, then simply enter its center frequency (i.e. 7.15 for the 40 meter band).
