Pictures say more than 1000 words - so have a look!!
DL5RBW is located in Reitgarten
right ON the borderline between Lower and Upper Bavaria. As you will have
difficulties to find Reitgarten
on your map here are 3 reference points.
It is located
15 kms south of Landshut
2. 20 kms
northeast of the NEW Munich International Airport
3. 50 kms northeast of the city of Munich
next to the Bundesstrasse 15 (B15).
The elevation is 516 m
(1693 ft) above sealevel and it has a population of about 40 people.
If the visibility
allows you can have a breathtaking
view to the North into the Bavarian (Bohemian) Forest or to the South into the famous Bavarian Alps.
Planning and constructing this
rotatable tower which in my opinion makes the most economic solution when
it comes to put up several antennas took about 10 years. Of course it wasn't
a full time job. Endless different approaches have been discussed, discarded
and started all over again. Finally we found what we were looking for.
Then the permission procedure began. As this was managed we could start
to erect the tower. That was back in 1994. Only used to average beam antennas
at average heigths in the past this antenna installation makes a significant
difference especially in the periods of low sunspot numbers.
"Homemade" 36 m (120
ft) rotatable tower made from 17 individual triangular sections each
2 m (6 ft) long. The sections are 88 cms (35 inches) wide and weigh about
45 kgs each. Hot dip galvanizing plus an additional coating of specialpaint
ensure a long rustless life expectancy.
are mounted to the side of the tower:
14 MHz: 6 Element Monobandyagi
at 36 m (120 ft) on a 16 m (52 ft) boom
21 MHz: 6 Element Monobandyagi
at 22 m (72 ft) on a 12 m (40 ft) boom
28 MHz: 6 Element Monobandyagi
at 17 m (56 ft) on a 8 m (26 ft) boom
24/18/10 MHz: 3 Element Yagi
- CUSHCRAFT A3WS at 26 m (85 ft)
28/21/14/7 MHz: 6 Element LogYagi
at 11 m (33 ft)
7 MHz: shuntfed boom of the
15 m Yagi
3.5 MHz: shuntfed tower
1.8 MHz: shuntfed tower
The equivalent electrical length
of the tower is supposed to be about
60 m (200 ft).
If time permits and if I am
not too lazy Beverage antennas are erected for receiving on the Low Bands
in the wintertime.
My thanks go to all who supported
me in this project and without whom
the whole undertaking wouldn't
have been possible:
my brothers Roland, Gerald
(thanks for software support!), my parents
AND my very patient XYL Gabriele.
Thank you for visiting the
homepage. I hope you enjoy it.
