Annecke Tuner

De tuner die ik heel lang gebruikt heb is van de firma Annecke. Helaas bestaat deze fabrikant niet meer. De Annecke tuner die je hier ziet is een inductiegekoppelde tuner. Dat wil zeggen dat er geen baluns in voorkomen. De overdracht gaat door middel van trafo werking. Op deze wijze is de set galvanisch gescheiden van de antenne.

De tuner heeft een ruim afstembereik maar is wel kritisch met instellen. De 4 bedieningselementen zijn wat omslachtig. Maar de tuner heeft een ruim afstembereik.

Hieronder een quoe van L.B. Cebik, W4RNL. Helaas silent key en zijn voortreffelijke website over antennes is nu moeilijk beschikbaar

Allow me to quote L.B.  Cebik, W4RNL here from his famous paper,
"Link-Coupled Antenna Tuners":

"Despite their relative scarcity, link-coupled tuners have certain
advantages over all other tuners. First, they are inherently designed for
use with balanced feedlines. Second, they exhibit very low losses, even at
high power levels with reasonable care of construction. (MY [Rick's] NOTE:
Annecke took meticulous care of construction). Third, they can be configured
to almost any balanced line condition that might face the operator". . . .
Furthermore (in comparison to the Johnson) . . . "The Annecke design does
away with the relay, receiver tap, and other pre-50-ohm transceiver
features. Instead, it uses a larger (overcoupled) link with taps for the
various bands (80, 40, 30-20, 17-15, and 12-10) mechanically linked to the
secondary coil tap switches. In addition, it employs a series variable
capacitor to adjust coupling (or input impedance, which amounts to the same
thing). The Annecke design is superior in this regard." Again, my [Rick's]
note: It appears that Annecke has, to date, produced the best-ever
matchboxes for matching symmetrical antennas to modern 50-ohm transceivers
or amplifiers.

The biggest problem Annecke had was that he did a very poor job of
advertising. Indeed, I cannot recall ever seeing a single ad in any ham
rag. It was word of mouth and participation at the larger ham fests (e.g.,
HAM RADIO in Friedrichshafen). Perhaps this is better so, because he and
his son hand-crafted all of the components and their manufacturing capacity
was limited.

As a result, many people tend to refer to "The Annecke Matchbox" or rather
the Annecke Koppler (in English, "Coupler") as he liked to refer to his
products, as representative for this symmetrical matchbox. CAUTION, not so.
This could be a big problem. Indeed, Mr. Annecke produced many products.
To the best of my knowledge, he produced 3 totally different versions of his
symmetrical matchbox (with multiple power versions of some of these), plus
two different versions of the 160m symmetrical coupler. He also made four
versions of the "Transmatch" (i.e., W1FB) rated 100, 300, 750 and 1000
watts. Then he had a "differential T" and an "L", etc. He also produced
many accessories to help in tuning and testing antennas for these
matchboxes. All in all his platform of matchboxes was probably second only
(in scope) to MFJ with build quality being on par with Palstar and several
levels above that of MFJ.

So when someone today offers to sell you an Annecke matchbox, be sure to
ask, "which one". Unfortunately the seller will probably not know how to
describe his box properly (because Annecke failed to do that as well).
Annecke did a very poor job of naming his children.

If anyone is confronted with this situation and wishes help, please contact
me. I will do my best. I have personally owned almost every product
Annecke ever built and still own 3 different Annecke symmetrical boxes, as
well as one 160m Annecke symmetrical box. I feel confident I can identify
any of his products with the answers to just a few questions.

The death of Alfred Annecke was a tragic loss for ham radio. It is as if an
entire era passed away. For a long time there was a vast void of
symmetrical products. Recently we have seen a flood of new products which
all in their own way, especially price/performance, are good, but all of
them share one common denominator: they are no Annecke. Each has one or
more negative points compared to an Annecke. The second common denominator:
they are all cheaper which probably makes them more appropriate for today's

I believe I have good product description of every Annecke Matchbox ever
built. I have it all scanned in, online, though some of the files are
large. If I ever find time, I would like to dedicate a web site to Mr.
Alfred Annecke. He certainly deserves it. Until then, anyone with specific
questions or needs can simply email me and I will do my best to help shed
some light on Annecke-related questions.

I hope this helps those of you interested to better understand the "Annecke

Long live OpenWire Feedline!

Those of you who have used openwire and had problems (i.e., with radiation),
please try again with a good (i.e., Annecke) matchbox. You may very well
change your mind over this type of antenna.

My final recommendation to all of you residing in America: As an American
residing in Europe for over 30 years, I can assure you that good stuff can
come from anywhere, not just from the states. Whereas I used to take pride
in seeing stuff "made in America", I now take the same pride in seeing stuff
"made by hams" regardless of the country of origin. It's global these days,
