Good news and some bad news  Time owned: more than 12 months
There are lots of good things to say about my 3-el with 30/40 meter option that I've owned for over a dozen years.

You soon get spoiled having a perfectly tuned antenna that automatically changes bands with you. I have gotten lots of exceptional reports from DX stations. I prefer this beam's performance to any of the various antennas that I've had through the years.

I chose the 3-el because I live in a very windy area. I'd like more elements, especially two elements on 40, but this is a good compromise.

For the bad news: over the past dozen years, I have had to replace the motors twice. Each time I replaced all three, figuring that if one was failing the others would soon follow. This is an expensive undertaking (over $1000 for the motors) because it also means paying someone to do the tower work (another $1000 or so).

This time I added their new junction box, a significant improvement over the old system. I am just disappointed that they haven't made their (expensive) motors more durable.

Groovy!  Time owned: more than 12 months
Bought mine used, it's worked perfectly the past year in +100 to - 25 Wx. No degradation from the high UV sun here.

The folded-dipole 40m option is very handy since I have no real trees and the 6m option works surprisingly well.
It's a full-sixed rotatable dipole on 30m which is good.

On 10-20 this thing shines! Couldn't be happier.
No reliability issues & the previous owner reported no issues.

Simply Amazing  Time owned: 0 to 3 months
Where to begin?

I purchased the 3 element yagi with 30/40 dipole.

The quality of the antenna is top notch. Not a single part was missing, and I had some extra left over (no I did not forget to put something in).

Performance so far has been amazing. I have been able to break pileups much faster than with any of my previous antennas. True, I have not been able to do an A/B comparison (except on 30 and 40) but I have been using a 3 element trapped triband antenna on a 12 foot boom regularly for the last four years and the SteppIR is a very big step up. My ability to hear is much improved and I am able to work stations in pileups much faster than before.

The front to back ratio is incredible. Stations that are a true S9 literally do not register on the S Meter once I turn the antenna 180 degrees. True, the S Meter on my rig is only about 2-3 db per S unit, but still that's a mighty big difference. When I turn the antenna a mere 20 degrees signals improve substantially, so the antenna is very directional.

I am absolutely over the moon with the performance of this antenna. Worth every penny!

Costly Repairs  Time owned: more than 12 months
Purchased my first 3 element SteppIR in 2009. In 2012 I decided that as I was getting older so a shorter boom was a better way to go so I decided to go with the 2 element model. Within 2 year and with very little use the antenna went deaf. Took it down to discover that both plastic driveshafts in the motors had broken. Called SteppIR and send the two motors in for repairs as the alternative was to sell the boom for scrap. The shipping was fairly expensive since I am as far as you can be from them. But the shipping was not the issue. The $500 repair bill just blew me away.

This is a great concept and the performance is fantastic but mechanically this product is clearly substandard as the shafts in the motors will fail. I am not a professional motor designer but the plastic shaft on these motors are very prone to fail and then SteppIR rapes you with the repair cost.

I paid $600 a year for the pleasure of using this antenna since between the repairs and the loss on the sale the total out of pocket loss was $1,200.00 for the privilege of having a SteppIR for 2 years.

So think about it as is not if but when the motors will fail you and then you will kick yourself when you get the repair bill. Took the easy way out and purchased a hex beam for less than SteppIr charged me to repair the motors.

My best Antenna  Time owned: more than 12 months
10 years have passed since I built this Antenna in 2007. I was satisfied with the performance,but
so far,I experienced two times of troubles.
One was trouble of Director ECU and another was that of Reflector ECU.
Those were caused by lack of material strength of Gear drive shaft,but,
I could obtain reinforced countermeasure parts and restored.
Thereafter,this Antenna works perfectly without any problem.

Great antenna  Time owned: more than 12 months
I have this great antenne for about 6 years.
I had the broken shaft problem with tape jam.
When this problem was solved it works perfectly.
What you hear is wat you work!!!

Solid Performer  Time owned: more than 12 months
First off, I've have had my Steppir 3 element 20-6 meter yagi since 2006. I removed a large 30 ft. boom 5 element quad array to put it up. You might say after listening to the talk I sort of fell in love the symmetry of the 3 element that you could reverse or go bi-directional. I could have got a 4 element at the time and sometimes I wish I did. But for what I got it has been the best beam I ever had.
I have had monobanders on 20,15 and 10 meters. I've had 2 element triband and 5 band quads (maco, home brew and lightning bolt, even once a gotham if you remember that). For the $1500 dollars I paid for the stepper it has given me the best over all service of any antenna I know. I am as some say a quad man in the quad-vs-yagi debates and still think about putting up another large quad array. There is something about pushing the limits that appeals to my nature and since reading Bill Orr's Quad Antenna Handboom I fell in love with them. I've also read his Beam Antenna Handbook too.
But my 3 element steppir has proved time and again what a great multiband antenna it is. I've done a lot of thinking about what you get for your money in these antennas. I know they are expensive. But over 40+ years of SWLing, BCBDX and ham radio chasing DX and contesting and rag chewing, I've come to believe you can't beat the steppir for all around performance. 6 bands on one antenna that is a monobander for your money. Think on that long an hard as I have.
I have had a controller chip die on the Friday that CQWWPHN was about to start in 2010; I have had to replace the driven element steppir unit due to intermittent contacts which I think was in the SO-239 and/or toroid balumn arrangement; a slight tilting of the beam needed correcting so I pinned the boom-to-mast bracket now; gone thru two tail twisters and a couple of Yaesu G-1000DXA's with their problems. This summer I brought down the steppir and repainted the fiberglass tubes as well as done some other things you can see on QRZ. For those reasons concerning the steppir 3 element I did not give it a rating of 5, only 4 which I really had to think about.
But pound for pound after years of use I have come to believe the steppir is the best beam antenna on the market. I get upset when something goes wrong but the support from Fluidmotion of their products has been outstanding. Constantly in my operating I get compliments like 'you are the strongest signal on the band' or 'you are 20 to 40 over' while running about 1200-1400 watts. I have a good setup with K3,P3 by Elecraft, a Command Tech HF-2500 amp, and the 3 element SteppIR at 78 feet. So I'm not running a dipole at 15 feet or whatever although I sure work a few of them.
But...for what it is worth I think the Steppir can't be beat giving you a monobander on six bands. I now have mine modified adding 12 feet of boom and two 6 meter directors as you can see on my QRZ page but basically, it's the same antenna I bought from the factory. Sooner or later I will likely add a forth element by adding an other 6 feet to the boom and directors on 10-20 meters. They aren't perfect but the support has always been there to back me up.
Owning an antenna like this requires the support of the makers due to it's steppir motor design and exclusive parts requirments. If I was to rely stickly on myself to maintain my beam I would probably be using another quad. But for 9 years now my steppir has proven itself capable of standing up to the rain, snow, winds, sun, time and all the rest and the money I paid for it was very well spent.
If you want an antenna that you can put up and have a monobander on six bands, it can be reversed and put in bi-directional configuration, and give you many years of service, check of the steppir products. FWIW, Terry, KI7M

Just superb  Time owned: more than 12 months
I initially purchased this antenna through Vine Antennas as a 2 element with 30/40m trombone.
as with Everything I purchase through Ron, the service is Second to none..
I had the 2 element up for about 2 years or so and I can honestly say that it worked flawlessly. I am a firm believer that full size elements (no coils or traps) is the best way forward, and I have not been disappointed.
In the 2 element design there is a noticeable gain/rejection over and above a dipole, and spent many hours with a local friend and Ham comparing with his hex beam, to which it seemed to be on Par,, with a boom of only 54" (4'-6" or 1.37m) it represents little more than A dipole in size to me.. I would park the SteppIR parallel with the house when not in use and that seemed to be fine with the neighbours.
At the beginning of 2014 I decided to purchase the 3rd element upgrade kit through Ron at 'Vine Antennas' (did I mention Vine Antennas ?).. The upgrade went without issue, everything was 'spot on' I didn't have to make any modifications to anything , it was a simple task. As I had to add more wiring and change one piece for a longer length, I decided to take the EHU's apart and check all was well.. Everything was clean and dry. 2 years at 40ft and no water,dirt or insect ingress at all..
initial tests were amazing, the first thing was the front to back compared to the 2 element was considerable, The beam width was also narrower and the forward gain very noticeably better (and believe me I am a skeptical bugger at best of times!!). It has been up on the mast now just over 12 months and I can say with honesty that it is an amazing antenna, and if I had to purchase again, it would be the same again.
As I said, it has worked flawlessly since initial purchase in early 2012 and with such great support from Ron I'm confident that I made exactly the right purchase. 5 out of 5.
