Quality made in Germany!  Time owned: more than 12 months
I have this beam for about 1,5 years and it is mounted about 4m above an OB11-3. Usually the tower is crancked up so that the OB2-40 is at 1/2 wavelength (20m above ground). This thing is a real pile-up buster :)

Put it together as per manual and it covers the full band as advertised. Also mechanically this is what I expect from "Made in Germany" :) The traps are build to last: solid material and construction used that will last long time!
Sure, you do pay more than other "comparing" products but the Optibeams are high quality and worth every cent!

I can only recommend this antenna and would certainly buy it again! Thanks Tom for another excellent product!

Another excellent yagi from Optibeam  Time owned: 3 to 6 months
I agree with all the positive remarks in previous reviews and see no reason to repeat them.
Compared to my previous 2 el. 40 m yagi it covers the whole 200 kHz with no higher than 1,6 SWR at both ends so I do not need my antenna tuner any longer and the 40 m decoupling stubs allows me to stack a yagi for the higher HF bands above it without any interaction.
I could not do that with my previous 40 m yagi without mounting it 90 degs. out of phase with the 40 m yagi, which was often leading to mistakes when I got tired e.g. towards the end of a contest.
I enjoy watching how stable the yagi reacts to strong windgusts of 30 m/sec with little movement when pointing the boom against the wind and along the elements as recommended by Optibeam.

Another Optibeam  Time owned: 0 to 3 months
Installed the OB2-40 at 120',the OB 11-5 is mounted on a second tower. The 40M Optibeam has the same outstanding build quality and performance. I have tried a variety of 40M antennas at this QTH...Bobtail Curtain, L, OCF and the Force 12 linear loaded dipole. With the Optibeam directed to Europe calling CQ often results in a pile up, a new experience on 40M.

Another Winner from Optibeam  Time owned: 6 to 12 months
Using this antenna in a contesting SO2R environment, exceeds my expectations for what a 2 element can do for perfomance. Mounted at 30 meters height, listening reception is excellent. Stacked above a OB16-3 unit, can be seen on QRZ. Top quality construction, you will not be disappointed.

TOP PERFORMER  Time owned: 3 to 6 months
After testing OB2-40 couple of months on the air, I have decided to put together a couple of words about this beauty. This antenna is simply the best what I have ever put on the tower.

Last 3 years I was building my own 2 el full size 40m beams and there is no gain difference btw. OB2-40 and full size - at least I can not feel any differernce. OB2-40 is even better if we discuss about F/B ratio and for sure better when we are talking about strenght. My last 2 homemade fullsized beams haven't survived one winter (strong wind and snow). OB2-40 survived last week wind with over 140km/h, yes elements are a little bit twisted but not much arr 5cm difference at the element ends.

If I compare OB2-40 with other antennas at my home, result and gain is as follows:

- full size GP (6radials, arr 5m over the ground) + 2S units
- dipole antenna, 20m up the ground +1S unit

The difference becomes even greater if I work long pass. With above antennas usually I have never heard Hawai, Alaska due to the high Alps close to my location. OB2-40 helps me to hear and actually go over the pile-up very fast (ACOM is helping me of course :-) ) also in this direction.

So, over all great performer, really strong construction, surviving wind, storms, snow and heavy pile-up :-).

You can see this beauty in the air on QRZ.COM...

Great Antenna  Time owned: 0 to 3 months
It's about 2 meters above Hygain TH-11, almost no interactions between two antennas. SWR as advertized and performance is outstanding (in my opinion better than my prior 3 elements monoband yagi from C.....).
Relatively easy to install and supports from Tom was excellent.
I am happy with this antenna

Simply The Best!  Time owned: 0 to 3 months
Ordinarliy I would not review a product that I've only had for a week but this antenna deserves it. I replaced a F-12 two element antenna with the Optibeam and the difference is incredible! The pattern is much sharper so I can actually reject unwanted signals. Front to Back is noticebly better as is forward gain. One might say this is just ancedotal evidence but I ragchew with the same group of guys every day and xmit/rx signals are consistantly better. I was able to work DX with the other antenna but again xmit/rx signals are higher with the Optibeam. Antenna resonance is exactly as advertised and the support from Optibeam owner, Tom DF2BlueOcean, is second to none. All my questions to Tom before and after the sale were answered promptly and in great detail. I would be remiss if I didn't mention quality. Again, the best I've seen. The workmanship and quality of parts and mechanical construction is fantastic. Night and day difference between this antenna and what I had before. Optibeams are expensive but worth every penny if you want the best. The antenna will outlive me!

Outstanding  Time owned: 0 to 3 months
The OB-2-40 is the second Optibeam that I've purchased and I've owned 2 other 2 element 40 meter antennas made by two different manufacturers. There is absolutely NO Comparison!

After putting it up, I got on the radio and beamed NE listening to a pileup on a Russian station. I made one call and the response from the Russian was humorous, as he started laughing and said, "WW4LL your a true 20/9 and are loud". I can go on about the performance as there are many similar stories already related to the performance of this beam.

However, I want to tell you that assembly of this beam and the OB 16-3 that I just put together is very intuitive as Tom has the boom marked where everything goes.

There are NO missing parts, no burrs and no excuses. It's simply First Class! The craftmanship is outstanding. Don't hesitate to buy one as I promise, you won't be sorry. No, I'm not on the payroll, I'm just tired of buying products that don't live up to the promises, no quality control and no one to stand behind them. Wish I'd bought these long ago, instead of screwing around with some of the others on the market.

Outstanding!  Time owned: 0 to 3 months
What a great experience, from ordering to operating! I contacted Array Solutions to get pricing and availability - Tom at OptiBeam immediately emailed me back to let me know there was one in stock in Germany. I ordered the antenna and Array Solutions set it up to direct ship to my QTH via UPS. I expressed my concern about damage to the antenna during shipping - Array Solutions said they would take care of any malfunctions.

The OB2-40 showed up and was exceptionally packaged - there were no missing parts and no damage. As I uncrated the parts, I noticed how meticulously everything was arranged and labeled - it made it very easy to inventory all the parts.

I soon started assembly - with very minor exceptions, this antenna almost puts itself together. OptiBeam has done most of the difficult assembly - everything is very modular and compartmentalized. OptiBeam also marked all the parts with permanent marker, which made identification a breeze. My only negative...and it's very there is some language disconnect in the assembly instructions - the translation from German to English had a few odd sentences that were difficult to understand. On a whim, I emailed Tom at OptiBeam to ask for clarification (on a Saturday) - to my surprise, I had a return email within 1/2 hour. Tom and I emailed back and forth, including sending some digital photos both ways for clarification. I have to say, I thought that level of customer service was extinct - Tom at OptiBeam did a great job helping me out. His remark to me that "OptiBeam is on the job 24/7 to take care of their customers" is no distortion of the truth.

Before mounting the antenna on the mast, I had it sitting on saw horses 3 feet off the ground, pointing due south. Just for the fun of it, I connected a coax and fired up the rig. I heard an HA station calling CQ, which was off the side of the beam. I tried calling him - to my surprise, he came right back! I couldn't wait to get this thing up on the tower!

Finally, my entire tower and antenna stack were installed. I fired up 40 meters in the evening and was not disappointed. With 100 watts, I worked 7 continents from Minnesota in about 2 hours. I broke through a significant pileup for RI1FJ and for Antarctica. In addition, when I called CQ DX, I experienced several significant pileups of my own. Everyone is giving me 5-9/599 + signal reports on only 100 watts, from the black hole of the midwest.

I highly recommend this antenna. On second thought, don't get one - it will give me a better chance to break through the pileups :-)

73s and good DXing
