Hi Ronald,
About two years ago I purchased new antennas. After doing some research, I
decided on three antennas from a German company, Optibeam.
I looked at Hy-Gain and did not choose them primarily because I was afraid
of the quality because of MFJ. Shortly after MFJ acquired Hy-Gain I called
MFJ to inquire if they had retained the engineering people from Hy-Gain, the
man on the phone said that anyone can measure and cut aluminum tubing. His
response scared me off.
I looked at Force 12 and thought they were too complex and way to much
assembly.
I considered SteppIR and was concerned about the moving parts that surely
will need service and that was out of the question. The SteppIR most
definitely will give you a perfect match since the controller keeps
adjusting the element lengths to maintain the 1:1 match.
I finally decided upon the Optibeam company from Germany. The Optibeam
line of antennas are sold here in the United States by Array Solutions, a
great company. I Purchased an 11 element beam for 10, 12, 15, 17, and 20
meters a 2 element beam for 40 meters and a 5 element beam for 6 meters.
The 11 element beam has 3 active elements on all bands except 10 meters
where there are 5 active elements.
I looked at the Optibeams about 10 years ago and backed off because at the
time they could only ship to an international airport and I would have to go
and pick them up and deal with customs.
This is all changed and arrangements have been made with UPS and they can
now be delivered to your home. I must tell you that the shipping cost and
the exchange rate on the Euro can add considerably to the cost.
Now, about the antennas, there are no traps, no moving parts, all hardware
is stainless steel and the aluminum tubing is heavy duty. All is of the
highest quality.
I owned a Hy-Gain TH6DXX about 30 years ago, before they used stainless
hardware and that was a pain. Also, the parts of the antenna were all just
dumped in to the box and one had to measure each piece of aluminum tubing
and match it with a drawing in the manual to determine what pieces to use to
build each element. What a pain in the A--. Hopefully, this is all
changed.
Now back to the Optibeam, the pieces for each element were bundled together
and marked so one knew exactly which element they would construct. The
element pieces slid in to each other and fastened with a screw in a
pre-drilled hole so no measuring was needed to get the proper length. There
were a few places where there were choices as to which hole to use depending
upon what part of the band you wanted to work. Even the position of the
elements on the boom was pre-marked with a sharpie. The Hy-Gain antenna
used compression clamps and you needed to measure each piece to get the
proper length, again, what a pain in the a--.
I am totally blind and was able to put 90 percent of this antenna together
myself after my son helped me identify what element packages were what.
As to performance, I don't really have anything to compare to. Haven't
tried to break through any big DX pile-ups yet.
The translation from German to English in the manual was a little strange at
times, not a big issue. I did have a couple of questions and e-mailed
Optibeam and got quick response even considering the time difference. All
communications is with the owner and designer of the antennas.
I met Tom, the owner in Dayton and he is great.
Well, this got a little long.
By the way, I looked up Optibeam on e-Ham before purchasing and all ratings
were a 5 except one. The only bad review was a 1 and it sounded like he was
an idiot. There were over 250 reviews. Over 250 reviews with a 5 ratings
says something to me.
