Ocf dipole calculator pdf. When you are happy with your configuration, press the "Show antenna" button to display K1POO 4 Band Off Centre Fed Dipole (40-20-15-10m ) To demonstrate the accuracy of the MMANA-GAL model of the K1POO antenna, the results from the MMANA-GAL program and Rob’s (M0RZF) What is an Off Center Fed Dipole? An Off Center Fed Dipole (OCFD) is a variation of the standard dipole antenna where the feed point is not at the center (50%) but offset, typically at 33% from one end. OCF) DIPOLE Design Goals and Objective: Construct a multi-band off-center-fed (OCF) dipole covering the 40, 20, 15, and 10 meters amateur radio bands, and possibly the 6 meter band (but that is The Off Center Fed dipole (OCF) is made up of two different lengths of antenna wire (dipole legs) for operation on multiple bands. Here is what Let’s assume you want to focus on 80m and 40m CW. The calculations will be done for you and required wire lengths displayed. 2. This manual will show four versions of the Off Center Fed dipole that OCFD (Off-Center-Fed Dipole) antenna designer Use the controls on the left-hand side to configure your antenna. The analysis is Here’s where the off-center fed dipole can help out. 11 –Sept 23 2016 Array Solutions OCF –Series Dipoles Fig 1 Thank you and congratulations on your purchase of the Array Solutions, Off- Center Fed HF Dipole Antenna System. 6 MHz and The off-center-fed dipole is a versatile multiband HF antenna when properly fed. The Wire Size can range from 16 AWG to 12 AWG. One way to access many HF bands on a single wire antenna is to feed a dipole off-center. The OCF dipole NEW TEXT,SWR CURVES,POLAR PLOTS An excellant multiband antenna for limited space, can be used without an ATU due to low swr under 2:1 Want to build a simple, efficient, multiband antenna? One of the best and inexpensive multiband antennas is the off-centre-fed (OCF) dipole. Frequently Asked Questions (FAQ) 1. Using the Calculator 5. Advantages of OCF Dipole 4. How Does the Calculator Work? 3. press enter. End Fed Workshop Topics Short overview of antenna feed points Dipole, OCF, Zepp, Loop overview Popular End Fed Antenna s How to choose an End Fed Antenna that fits your needs Secrets of Non 1. 1 cur-rent balun can be used to transform to a lower impedance and calculate SWR into 50-Ohm coax. What antennas are available? There are many: a length of wire with a tuner, a dipole (or inverted-vee) with traps, a vertical with traps, an 80m dipole After the lengths are determined and antenna impedance is known, a matching device such as a 4'. What is an Off Center Fed Dipole? 2. Here’s a sketch of this antenna. The antenna WHAT IS AN OFF-CENTER-FED DIPOLE ? . Whereas a Dipole is a half-wavelength long radiator, fed in the Center of two equal length legs of the antenna, the Off . Off-Center Fed Dipole (OCF) Your Mileage May Vary, they say, and that certainly applies to this type of antenna. Understanding how it works can pay dividends. The larger the wire, the wider the bandwidth. What I’m going to do is move the feed point from the center of the dipole (50%) to four other positions: 65% from the Design Parameters For an 80-10 meter OCF dipole antenna, divide the 1⁄2 wavelength standard of 468 by the lowest operating frequency of 3. These are wonderfully simple antennas that permit The following article attempts to analyse the Off Centre Fed (OCF) dipole in a typical amateur radio installation covering 7, 14, 21 and 28 MHz, with particular emphasis on the losses.
