It is just that, compared to EZNEC, 4NEC2 and the likes .. any one of VE3SQB's programs is so darn easy to use! :-)

In addition, his software installs without messing with Windows' registry .. which means you can delete the executable files just like any other file. Nice touch!

VE3SQB is to be complimented for his work and for caring for the 'non-initiated'.

Last time I had a look at his collection of programs on his site, I counted 24 executables!

I only cover a small selection of his
useful antenna software (below) ..
enough to whet your appetite, I think!

VE3SQB
Antenna Software

Al Legary - VE3SQB - admits that he is a 'quad' man.

Having had a GEM Quad (HF 20-15-10m) for a few years, back in the early 80's, I can testify to the quad's slight advantages over a tri-bander Yagi with the same number of elements.

My experience has been that a well designed, 3-element tri-band quad has..

  • Noticeably broader bandwidth response below a 2:1 SWR than a Yagi.
  • Better performance in QSB and marginal conditions than the Yagi.
  • Overall better on receive than a tri-bander Yagi with traps. Certainly much quieter! (Picks up much less QRN).

Al has more to say about 'Why Quads'? at the following URL.
( http://www.ve3sqb.com/whyquads.html )

Please note that VE3SQB's software is for Windows™ only.

Quad Design V3

Using Version 3 of his quad design program is very straightforward.

You just set the frequency for which you want to design a quad, indicate the number of elements, the wire size, and choose the type of gain you want.

Then, hit the 'Calculate' button. Presto! All dimensions appear in the table on the right hand side.

As with most of his programs, you can choose between English (feet, inches) and metric measurements.

A graph (bottom right) shows a SWR curve within the 'working' frequency range of the quad.

Like I said. Pretty straightforward antenna software.

The 'Sky Hopper'

Al named this antenna 'Sky Hopper' because it resembled a grasshopper!

The antenna is essentially a quad with the bottom removed, leaving 'U' shaped elements.

Al recommends this antenna for beginners, as it is very 'forgiving' to small departures from the dimensions given by the program.

Maximum radiation from the 'Sky Hopper' is off the corner opposite the feed.

OmniQuad

The 'OmniQuad' is omnidirectional. It is very broadband and dimensions are not critical at all, even at VHF and UHF frequencies!

A 'fun' design to experiment with.


Capacitor Designer

Extremely useful utility program for the experimenter because capacitors suitable for the high voltages present in antenna systems and antenna tuners are hard to find .. and very expensive when you do find any! :-(

But now you can make your own!

Neat, huh!


You will find VE3SQB's entire collection of useful antenna software here.

EZNEC v5.0

This is my review of the EZNEC v5.0 antenna design program.

The 'demo version' of the software is fully functional and more than adequate for most ham radio antenna design needs. Oh! And it's free! ;-)

Once you get familiar with all the capabilities and features of the demo version, you will have acquired the know-how to design more complex antennas.

In fact, EZNEC v5.0 is so powerful that you can design complete antenna systems consisting of..

  • the antenna,
  • it's transmission line
  • and even the impedance transformer ('antenna tuner'), if required.

Demo Video

A picture is worth a thousand words. But a video is worth a thousand pictures.

Therefore, I produced a video demo (see below) to introduce you to the EZNEC v5.0 free demo version.

In the video demo, I use the program to design a 20 meter dipole which is to be installed 30 feet above ground.

The video will take you through the basic steps.

  1. Initial setup of antenna and environment parameters.
  2. Basic antenna design experimentation.

Note that you can do a lot more
with the EZNEC v5.0 free demo version
than what I will show you in the video.

The documentation is very complete and well written. It is in the form of Windows help files. The contents are very well structured and easy to navigate.

You can follow the help as if it were a tutorial in antenna design. You can also skip and jump to specific sub-topics using the detailed table of contents.

Now. On with the show .. Lights! Camera! Action!

Please note that the video may take a some time to load if you do not have a broadband Internet access.


I have had to limit the resolution to limit the size of the file . . . which explains why the final video is 'a little fuzzy'.

You will admit that the demo version of EZNEC is very powerful, as is! On top of being educational, the software will enable you to analyze and design most of the common types of antennas that amateur radio operators use.

When you feel comfortable with the program, and like what it can do for you, then you can go for the commercial version which will enable you to explore much more complex antenna systems.

Other Noteworthy
Antenna Software

I decided to investigate antenna design software because I was tired of the traditional 'cut-n-try' method.

That was fine during my first quarter of century as a ham radio operator and antenna enthusiast.

But, now in my sixties, I feel I need to make more efficient and effective use of my time. ;-)

Many consider antenna modeling programs to be 'overkill' for most if not all ham radio antenna experimenters needs.

Not me (obviously).

The first benefit you get from using a good antenna design program is a much better understanding of all the parameters and compromises that go into the design of an antenna system.

By the way, one learns that there is more to an antenna system than the antenna itself!

The 'Zero Cost'
Antenna Design Software

Here then are some of the most popular 'no-cost' programs that are available today.

To be honest, there is a cost to this type of software. Your time! You will have to invest a bit of time up front to learn..

  • What the software can do and what its limits are.
  • How to navigate through the user interface.
  • How to get the most out of any given antenna design software.

But the time invested in learning how to design your own antennas will bring very appreciable returns.

  • Precious knowledge and know-how.
  • Self-satisfaction of having mastered yet another aspect of ham radio.
  • Not to mention designing and building antennas that will sometimes outperform commercial ones!

NOTE
The following antenna modeling software
run on Windows only!

MININEC

In 2014, Roger, WB0DGF, released an improved version of MININEC which he named mNEC v.1.0. The previous version of MININEC dated back to 1999!

Roger's version is certainly worth looking into if the above mentioned software does not meet your requirements and expectations. His version of MININEC will run in Windows XP, Vista, 7 and 8!

You can download mNEC v.1.0 on WB0DGF's site.

4NEC2

The user interface of the 4NEC2 Antenna Modeler and Optimizer .. is not quite as user-friendly as EZNEC's.

On the other hand, 4NEC2 let's you subdivide your antenna into 1500 segments (default)! That means higher accuracy and the possibility of modeling complex antenna systems.

Yagi Antenna Design software, free download

Want to run more than the default (1500!) number of segments? See the FAQ on the site. Note that the 4NEC2 software will run on Windows operating system, versions 95 to Vista. I have not tested it on later versions. Try it anyway! It might work.

Available at: http://www.qsl.net/4nec2/

Some things still come with a price tag in this world! The antenna software packing those little extras you just can't live without is one of those things!

Here are two examples.

MININEC Pro

MININEC Pro, by Black Cat Systems, will run on both Windows and Mac OS X.

Available at: http://www.blackcatsystems.com/software/mininec.html

RF Workbench™

This shareware is for for the engineer in you!

Note: RF Workbench™ will not run in any 64-bit version of Windows w/o an emulator!

Reading Material

Yagi Antenna Design software, free download Windows 7

The designing and building of antennas is a very wide subject. It has become a hobby within a hobby for many of us.

Much has been written on the subject.
Some of it cannot be ignored. For example..

ARRL Antenna Handbook

I strongly recommend that you read Chapter Four of the ARRL Antenna Handbook. The chapter is dedicated to 'Antenna Modeling & System Planning'. It will help you understand antenna modeling and evaluate the antenna software available.

AntenneX

'AntenneX' is a online magazine dedicated exclusively to everything related to antennas.

An absolute must for true antenna enthusiasts who need to get the most out of their antenna software, especially those at ease in a more technical environment.

LinearDipole - set length to 0.5(half-wavelength dipole) and notice that theimpedance is near 73 ohms. Radiation pattern shown is typicalfigure-8pattern. When a half-wave dipole is close to ground, the impedance isloweredto near 50 ohms. Thus a perfect match to 50 ohm cable.

-set lengthto 1.27 wavelength. This is called an Extended Double Zeppantenna and produces the maximum gain possible from a simple center-feddipole. Notice that the radiation resistance (impedance) is about 90ohms. This antenna can be matched to 50 ohms by using a seriesinductor.Half of this antenna is 5/8 wave and is a common length for 2m mobileantennas.The 5/8 wave antenna is typically fed against a ground plane (car roof)andis usually matched with a tapped inductor.

-set lengthof dipole to multiples of 1/4 wave on each side (e.g. 0.5, 1.5,2.5, etc.). Notice how these lengths produce an radiationresistance(impedance) close to 100 ohms. The patterns of these are madeup ofmany lobes (cloverleaf pattern).

The following files and links point to NEC/AO/YO models of various Hamantennasthat I have simulated and/or tested over the past 30 years as anantennadesigner. The NEC files may be used with any of the NEC-2 or NEC-4programssuch as 4NEC2, GNEC or cocoaNEC, however some of them with taperedelementsmay only be simulated accurately by NEC-4 or other MININEC-basedsoftware.These models will indicate in the CM lines if they need to use NEC-4 or4NEC2.These models have varying degrees of accuracy. Some may be very closetoactual performance. Others may only be an estimate. They are for you,asthe experimenter, to use and improve.

The VHF antennas shown above include the 'raw' element lengths. Thatis, the element lengths are those used with a wood or plastic(dielectric)boom or supported above or below a metal boom with an large insulator.Toconvert these raw lengths into actual lengths used when passed throughthecenter of metal booms, you need to add a correction factor, based onwhetherthe element is insulated and passes through the center of a metal boom,oris shorted directly to the metal boom with a clamp.

If theelement is insulated when it passes through the metal boom, thecorrectionfactor is approximately 1/4 the diameter of the boom. Forexample,for a 36' (raw length) insulated element passed through the center of a1'metal boom, the correction factor is 0.25', so the actual length shouldbe36.25' when built.
