Off Topic - Antenna Design Software


Brian Howell
 

I am thinking about designing and building a Yagi antenna for 54.310 MHz, I don't need much gain, just a simple 3 element antenna.  I have asked around and have been referred to a few online calculators for Yagi design.  Today I found a pretty good Excel calculator http://on5au.be/content/a10/trans/ant-design.html  that is not just a cookie cutter calculator like the online versions which is better but I would also like to be able to see the radiation pattern and SWR graphs. 


I tried for many hours on Monday to design the Yagi in 4NEC2 because it has a CAD type interface for creating the antenna, which I like but it still leaves a lot to be desired.  I got hung up on running the optimizer, it was asking for variables but they were blank and I have little idea of what I should put in there.  I found a couple of online tutorials but They did little explaining on the ins and outs of the variables that is supposed to be entered into the program.


I did a lot of searching online today for an easy to use program, I guess with my getting older, my brain is hardening a lot more than it use to because I am having a lot of trouble to orient my thinking to be able to use even 4NEC2.  All of the "free" programs are difficult, not user friendly, or just won't run on Windows 10. 


Today I found a program called PCAAD 7.0.  http://antennadesignassociates.com/pcaad7.htm  I couldn't find any reviews for it, The user manual has some explanation on how the software works but I would have to buy it in order to really try it. At $549 it is a bit steep, however it "appears" easy to use and covers a lot of different antenna types, including Yagi type.  So my question is: Does anyone have any knowledge of this program? or has anyone used it before?  Is it really easy to use?  And does it do a really good job?


Thanks,

Brian Howell

I should think that unless you are in an engineering lab, with a
corporation to pay for your software, it would be
ridiculous to buy PCAAD.  Buy a copy of the ARRL Antenna Book from the
ARRL. It probably has a 3 element
yagi for 6 meters in there--just shorten the elements a tiny bit to get
to 54.1MHz. What's there, anyway?

Brian,
Have a look at :-

The program is based on the work of DL6WU, The farther of amateur Yagi antennas.

If you want to pay try EXNEC. For most uses MANA-GAL has good support. And there is a free version.

Brian,

If that is all you want then any design that suits you will work.
Simple Yagis are well understood, small variations in construction will have no practical effect on performance.
As Doug says, scale down a 6m design.

mmana is easy to use ... free ... and has a nice editor

if you ever used any "paint" software in windows then you can use that editor (click at start of line, hold mouse button to pull your line and release at end) ... very easy in my view

I am wanting to put together a forward scatter meteor detection system.  I will attempt to pick up reflected TV pilot carrier signals from channels 2-6, particularity channel 2.  I will look up the antenna book.

Typo alert that's EZNEC. Note that these programs can be rather addicting. And the quality of the output varies with the quality of the input, including complete description of the antenna and other metal objects in the area.

The  [MMANA-GAL] groups.io list MIGHT be of interest.

But for a generic three element yagi the "ideal" radiation pattern is very well known and widely published. What you will get in reality is modified by your surroundings. And a complete description is "daunting" and can overload most simulation engines and computers. The easy way out is to take a standard design with the characteristics close to what you want and run with it. I doubt fractions of a dB differences are going to affect your results to any huge degree.

Thanks!  I will take a look at the group.  I'm waiting on the updated version of NanoVNA V2 before I buy one of those, that will help a lot I believe, if I am able to build an antenna.  At least I'll be able to measure the impedance and SWR of what I make to see how close it is to what I am wanting.  I have no test equipment to speak of when it comes to antennas so whatever I make may inefficient in many ways.  I'll have to look into how the driven element is attached to the coax.  I've read that two strait rods are around 75 ohms or so but fold them and they are around 300, I remember that from the days of when I was wanting to build mu own TV antenna way back in my teens and twenty's.  With 50 ohm I've seen pictures of a dipole with a third short rod attached to one side under one of the dipoles and some with ferrite rings, ect. .    I'm just hoping all I need to two dipoles to make it simple.

Thanks,
Brian Howell

The  [MMANA-GAL] groups.io list MIGHT be of interest.

But for a generic three element yagi the "ideal" radiation pattern is very well known and widely published. What you will get in reality is modified by your surroundings. And a complete description is "daunting" and can overload most simulation engines and computers. The easy way out is to take a standard design with the characteristics close to what you want and run with it. I doubt fractions of a dB differences are going to affect your results to any huge degree.

mmana is easy to use ... free ... and has a nice editor

if you ever used any "paint" software in windows then you can use that editor (click at start of line, hold mouse button to pull your line and release at end) ... very easy in my view

I tried for many hours on Monday to design the Yagi in 4NEC2 because
it has a CAD type interface for creating the antenna, which I like but
it still leaves a lot to be desired.  I got hung up on running the

not user friendly, or just won't run on Windows 10.


Today I found a program called PCAAD 7.0.
http://antennadesignassociates.com/pcaad7.htm I couldn't find any
reviews for it, The user manual has some explanation on how the
software works but I would have to buy it in order to really try it.
At $549 it is a bit steep, however it "appears" easy to use and covers
a lot of different antenna types, including Yagi type.  So my question
is: Does anyone have any knowledge of this program? or has anyone used
it before?  Is it really easy to use?  And does it do a really good job?

Also look up the Gamma Match Brian.

It’s how the best match was obtained with the old MET antennas in the 80’s.

Mechanically quite easy to do with the driven element connected to the boom electrically.

I can help more on describing this but I’m on another mission today.

Ahhh okay.  Thanks!  Yeah, that was what I was talking about. . .   I'll have to study up on that.

This thread reminds me of a sticker on the helm of my Tiki Barge (next to the blender on the bar):



Since you are NOT transmitting, SWR really doesn't matter all that much. Why not use the tried and true method of a dipole cut for 54.310Mhz and the reflector 5% longer and director 5% shorter. The spacing set to .125 the wavelength on the director/reflector distance to driven element.

We use the above numbers for our 3 element 40M wire beam at Field Day every year with great success as both a TX and RX antenna.
Occam's Razor comes to mind here as well as the KISS method.

You may be right.  Since I have never built an antenna like this before I'm also using it as an education tool for myself.  I'd like to know enough and learn enough so that if another project comes up in the future I'll be able to run a design program and spit out an accurate model that I know is correct to build a different antenna.  Since I have no personal reference for what works and what doesn't or what is good enough and what is overkill I am leaning toward overkill as a reference then backing off as I gain experience and knowledge.  If I am able to complete this project and learn more about antenna design and if I build other antennas in the future I may get to the point you are now and look back at this and say "I was going way overboard, I could have just plugged in some ratios and I could have saved myself a lot of time and trouble".  I guess I have to start somewhere, I just feel better about a project when I have an idea of what works and what the outcome will be.  I would hate to spend all this money on tools, metal stock, and hours of effort only to find out that a coat hanger does a better job than my antenna and not knowing why my antenna did so poorly.

Brian,

That's the way!
Use straightened coat hangers, I'd bet you would find it very difficult to prove a "proper" antenna was better.

Coincidentally I recently built this quick and dirty 8 element Yagi for 434 MHz. I used pieces of 14 gauge wire for the elements, coat hangers would have been better :)
