Powerful antenna. German Mechanical Construction Quality  Time owned: 0 to 3 months
My ob 30-1 is just 2 meters high from the x7 for this reason Tom suggested the use of a balun 1: 2
Antenna arrived in very few days with bomb-proof packaging.
Detailed instructions, very easy to build with precise and well-matched pieces.
Very robust mechanics
Mounting time of about 1 hour
Just positioned on the tower Ros Plate on the whole band (swr 1, 4)
Turn on the radio and in the first 30 minutes of trial have gone to log 3c1l and vk9cz
I have performed a comparative proof in reception between inverted v full size dipole and ob 30-1. Ob 30-1 always has higher signals up to + 3 points S on some stations.
I would say that I am very pleased. The price is justified by project quality, design and customer service always present. Tom responded to my mails in a very short time, including Saturday and Sunday.
Great antenna with very high performance

Amazing!  Time owned: 0 to 3 months
Assembling the OB1-30 was a breeze, the manual is very well done and everything fits together nicely. I like the way the tubes are bolted together - a simple, but very efficient, reliable system. It took a little more than an hour to put it together and install it on my tower (at 45 ft). Then came the big surprise: signals came in about two S points stronger than with the inverted vee. My first QSO was with a JA. Then I called CQ DX - and generated a small pileup! This antenna makes me feel like a big gun... A shortened dipole? Yes, but the low-loss coils make all the difference!

I can only recommend this antenna and add another 5 stars to the many stars OptiBeam already has on Thanks, Tom, for an outstanding product and service.

super !  Time owned: 0 to 3 months
Not that much to say, except that this is again Optibeam Quality

assembly : about 45 minutes, tower mounting included
swr : 1.2:1

I just tested the antenna (only 11m high due to high winds) during 30 minutes with 1KW:
36 QSO's made : 17x JA, 4x PY, 1x ZL and 14 european stations contacted.

Of course on 30m everyone plays in CW, but for me this proves the OB1-30 efficiency.

Thanks Tom for the nice design !

technology on its best  Time owned: 0 to 3 months
I have this dipole mounted together with OB1-40 on a boom section about 2m on top of a OB-11-5 about 20m over ground. It is really a amazing, how easy it is to assable and to use. Worked 5 new DXCC (#244) in the first week: This one is a pileup killer!

I LOVE OPTIBEAM  Time owned: more than 12 months
All what I have said in my review regarding the OB1-40 I can say about the OB1-30 as well. I have no space for a 40/30m Yagi, if so, for sure I had the OB4030 up on my tower.
But the OB1-30 already makes you feel like being one of the louder stations on 30m, it seems to be much more than just a rotary dipole. And what I have said concerning my OB1-40 counts here as well, without any doubts for me it is like day and night comparing the OB1-30 to a lossy vertical or a poor inverted vee.
Dxing with the 1-30 is fun. As short as the element is, the secret again is the high Q coil which is used to shorten the element, and which is the same coil used on the OptiBeam 40m element, a real piece of art.
Since I have the OB1-30 up on my tower I enjoy dxing on 30m, I have directivity, apparently I have a loud signal, and so I have a lot of fun. You want to work more than 245 countries within two years on 10 MHZ? Then go ahead and install an OB1-30
