This reduced ground-loss significantly. The coil is made of different kinds of wires.

In total, the coil has about 300-400mH, depending on actual set-up. Ossi is using one of the top-load wires of the existing LF antenna (20m vertical) to have it lifted by the balloons.

Hello Gerhard, Ossi,

maybe a "helikite" can help ?<= /font>

Hello group!

Ossi asked me to give you an overview about his set-up.

We spent many ours on the phone during the past weeks and I assisted him in building the system.

The PA is a car-audio equipment running at 25A / 14V followed by a
toroid-transformer about 5T/50T. Transmission line is abt. 30m of
existing RG58 (also used for LF). The inner wire connects directly to
the cold-end of the loading coil and the shield is connected to the
existing grounding-system (a lot of buried wires), which was enforced by many (>100) square-meters of wire-fence and wire-grid (usually used for=
plastering walls) laying on the lawn. This reduced ground-loss
significantly.

The coil is made of different kinds of wires. The main-coil is made out of 0,6mm enamel wire wound on a plastic water-barrel (abt. 400liters)
and there are 2 or 3 smaller coils made of installation-wire which are
coupled to the main-coil by varying the distance. In total, the coil has about 300-400mH, depending on actual set-up.

Ossi is using one of the top-load wires of the existing LF antenna (20m vertical) to have it lifted by the balloons. The balloons are made out
of latex (9=80) having a volume of abt. 1m=B3 when totally inflated. If so= ,
one balloon will lift 900 grams of weight. One Helium-bottle is abt. 4m=B3=
and the price is abt. 120=80. Ossi found out that it is better not to use<= br> one balloon totally inflated but rather two of them only inflated to
half of the volume. This is reducing gas-loss trough the shell
significantly because the material is not stretched so much. He filled
the first balloon a week ago and didn't notice any degradation until
now. So my guess is that they will be usable for at least 2 weeks.

The only problem is wind. Even when you can't feel the wind on the
ground, as soon as you reach 50m, the balloons will drift away caused by wind, thus lowering the height. Ossi lives in a region where days with
absolutely no wind are rare. Yesterday wind was weak and so he reached
nearly 80m at nearly 90 degrees.

Ossi measured the antenna current but only with some "multimeters&quo= t; and
I'm not sure how accurate they are. From the reading of the those
meters, the antenna current is 1.6A at full power which is rather high.
Knowing Ossi, I'm sure he will improve the setup during the next weeks
and so you can expect more and stronger signals from OE.
