This website is a collection of ham radio antenna projects and ideas that I have used, built and/or designed over the last 50+ years, along with supporting theory and construction practices. It reflects my personal interests, particularly portable antennas, antennas for emergency communications, and for radio direction-finding. It also reflects my personal philosophy of antennas, including:
I take a pragmatic approach to antennas: sometimes you do whatever you need to do, using whatever materials are available, to get on the air, even if it isn’t “perfect”. That doesn’t mean ignoring theory and good engineering practice, but rather taking them into account when one makes trade-offs, so you know what potential problems you may encounter when it is more expedient to do it differently.
We are all beginners at some point
Most of us didn’t understand antennas until we started using them. There is nothing wrong with being a beginner: I’m working to make this site more accessible for newcomers. I think of antennas like an onion, with different layers. As you go deeper, you realize that some of those “truths” that you learned about antennas initially might have worked to get you started, but aren’t really the whole story. There is always more to learn.
There is no one right answer
Hams use antennas for a wide range of purposes in many different circumstances. What works well for someone else might not be a good solution for you. I encourage readers to analyze their specific requirements and choose an antenna accordingly. Sometimes a small change in requirements might call for a totally different antenna. Hams may make different trade-offs between convenience and performance, or other factors. And the truth is, there are many cases where several different antenna designs may work about the same, so it really doesn’t make much difference which one you use. That’s important to know, too.
Theory or Practice? Both.
I don’t expect all my readers to be electrical engineers, but some understanding of theory is important (particularly to help protect you from some of the many falsehoods and misconceptions one often encounters). I’ve tried to provide some of the basics, especially the useful bits that you don’t find elsewhere. I also strongly recommend experimenting: put up two antennas and see which works better for your specific needs. That’s one reason I focus on antenna construction methods that are easy to put together, and then to recycle the parts later for a different antenna.
Don’t worry about copying my projects exactly.
Unlike some other web sites, I don’t expect readers to copy my projects exactly as I built them: I try to provide a number of options for how they can be built, so the builder can use whatever materials and skills are available to them. You can probably find a better way to do something than I did!
Making mistakes is a good sign.
It shows you are trying something new. Hopefully you learn something from it.
“You never learn less.” – R. Buckminster Fuller
I’ve made a lot of mistakes over the years: antennas that didn’t work as expected; antennas that didn’t work at all; antennas that fell apart while driving down the road; burning my finger on the hot coil in my antenna tuner; getting wires stuck in trees; getting myself stuck in trees when trying to rescue my wire; collapsing on the ground laughing when the spreaders for my cubical quad were too limp to hold themselves up… the list goes on. Some mistakes are more public than others: when you have 6 hams helping you put up an antenna, it is more embarrassing that it doesn’t work. Or when it radiates the wrong direction. But making mistakes is an important part of learning. Acknowledge them, laugh at yourself as you figure out what is wrong and fix it (or start over), then go on to make different mistakes next time.
No antenna is permanent.
All antennas are temporary, whether on a scale of hours, months, or decades. Of course, sometimes my “temporary” antennas have stayed up longer than my “permanent” ones. Assume that you will take your antenna down periodically for tuning, repair, maintenance, or to try something else. Then design your supports to make that easy to do. Where practical, use a halyard (like a flag pole) to raise and lower your antennas..
Also, don’t worry about choosing the “perfect” antenna the first time you put one up: it takes time to develop a feel for what aspects of ham radio you might find of most interest (and that changes over time), so your choice of antenna may change as well. I encourage hams to put up temporary antenna to see how a particular design will work for them, then build a more permanent version if it is a success.
Feel free to modify these projects, adapt the ideas for different bands, or develop your own designs based on this information. That’s my purpose for writing all this in the first place.
