Mmana fan dipole, There was a fair amount of gap between each element, probably about 5 to 7 degrees becasue that’s what I thought you should do. MMANA-GAL is an antenna-analyzing tool based on the moment method, which was introduced in MININEC version 3. May 19, 2014 · The book looks at the free MMANA-GAL antenna modelling program that lets you design and optimise a whole host of antennas – all on your PC. . HOW TO: NOTE: I like to draw a small feedpoint in all my HF antenna models, like a 5cm length of wire where my “source” (coax) is connected to. This is a collection of my antenna simulation files in MMANA-GAL and 4NEC2 Files with . Using MMANA, I created a model and it appeared to work in software. The main advantage of a fan dipole is that it’s a plain old dipole. Last year, with the assistance of Stu, M0NYP, I built a fan dipole out of D10 military telecoms wire for 80m, 40m and 20m for club field days. It shows you step-by-step how to input antenna designs into MMANA-GAL, how to adapt designs you are given and how to optimise your designs for the best performance. We’ll cover the theory, calculations, materials, construction, and the crucial tuning process. Contribute to Kees-PA3KJ/EZNEC_Files development by creating an account on GitHub. Plan for a basic fan, or parallel, dipole. nec are 4NEC2 compatible. It will be center-fed with ladder line and an antenna tuner with internal balun. But I use that name instead for the original fan dipole. This is a collection of my antenna simulation files in MMANA-GAL and 4NEC2 - AntennaFiles_for_NEC_MMANA-OLD/1E40 broadband GM Dipole. The antenna will be useable from 20 through 6 meters with gain and a circular pattern. To optimize the positions of the traps of a multi-band dipole specified on the Geometry page, the two traps will need to be repositioned equally about the center of the antenna using two variables, Y1 and Y2, to specify the trap positions, and dipole center must be at Y = 0. Jul 28, 1995 · EZNEC antenna description files. Particularly useful for fan dipoles and for making other Modeling was performed on a vertical dipole, with elements tapered, over average ground, using MMANA. This will greatly reduce feedline losses. maa extension are MMANA-GAL type and . Nov 23, 2025 · This guide will walk you through building a fan dipole for the popular 10, 15, 20, and 40-meter bands. I’d like to thank Sigi, DG9BFC for clearing this up for me. The program use the MININEC-3 engine modified by Alexandre Schewelew, DL1PBD, and are written in C++. 47K subscribers Subscribed I wondered if the “fan” in fan-dipole was a myth? I thought about placing the 10m elements on one side of the fishing pole and the 15m elements on the other side, about a 25mm separation, tapering down to about 20mm separation near the ends. I’ve been scratching my head for years how to model an appropriate ground with my ground mounted Vertical Antenna radials. That means it’s balanced so you don’t have to battle with excessive common-mode current on the feedline as you would on an off-center fed design. maa at master · agettikh/AntennaFiles_for_NEC_MMANA-OLD Dec 11, 2024 · This is sometimes called “fan dipole”, even when the antenna wires aren’t arranged in the shape of a fan. Apr 8, 2020 · Designing a fan dipole for 40 meter and 20 meter using MMANA-GAL Aniruddha Bokil VU3FML 1. The BASIC source code of the computation engine is published as a PDS in MININEC.
