Biography

Hi - my name is: Wolfgang Alexander Michael Boettcher -
but please call me with my christian name: Michael

Address: Untere Bergstrasse Nr. 6, D-88693 Deggenhausertal, Germany nr Lake of Constance, born in: Gelsenkirchen / North Rhine-Westphalia / 1951. Lis. since: 1969 / DC9JO - 1972 / DK5IQ - DOK: A44

Profession: HF- and Electronic-Technician -

I´m developer of some new Shortwave - Wire - Multibandantennas:

Following Antennas are really usable to feed with coaxial-cable or with wireman-feeder-line over a Z-Match or for example the S-match from PA0FRI, because of the realized resonance in every HAM-Band.

1. MAD-YAGI a Multiband-Wire-Antenna for Z-Match-coupling with integrated

3-Elt-Wire-Yagi for the 20m - Band

2. The RADIATING-ROPE-LADDER

Multiband-Folded-Dipol with tuneable Stub -

First identification of the antenna was: "CGFD"

C - combined G - grounded F - folded D - dipole

(see CQ-DL 2001)

3. Another baby from DK5IQ - isn´t only the name of my daughter:

"The "JANET-enna"

J -ourney A -ntenna N -etwork E -asy T -uneable

4. One type more is the MDL Multiband-Double-Loop in 3 versions with

embossed resonance frequencies without any real traps!

The description has been published in the HAM - Magazine:

"FUNKAMATEUR" FA 11 / 09

3 - Versions: MDL-S a double-loop

5. Today i am using an unsymmetric feeded dipol only 35m long and works fine -
called: "THE BLACK-FOREST-WINDOM - 160m upto 10m without 20m-Band.

6. Brand-New in 12 / 2013 is ready for order a new type of Multiband-Magnetical-
Loop-Antenna its a travel and Indoor compact-system - tunable from 3,5 to
150MHz - Actual Type ist the MML-8010-S-246 . An Aerial to use it for
Short-Wave and you can switched to VHF - so the Loop is a Lambda-Loop for
2m-Band with 1dB over a Dipol. The description has been published in the
HAM - Magazine: QRP-Report 1 - 2015

7. Last and brandnew portabelversion made by DK5IQ of the VHF - DL7KM -antenna
is now ready. The description you can find in "Funkamateur-Magazin 10/16

Worked DXCCs:

Equipment

My Station currently:

Antenna: Multiband- off-center-feeded- Dipol / 40m - standard-dipol and TH3jr

TRCV: FT-991 HF/VHF/UHF / FT-817ND
RX: SDR-PLAY -RSP2 / SDR-Harzburg with hm Preselector 1,5 - 30 MHz / FiFi-SDR
in PSK31 i used allways max. 10 Watts EIRP with FT-991 or FT-817ND
