33 meters of twin wire 300- Ohm TV Cable was wound
around a bamboo fishing pole in 5 meter length. Line on the antenna
up end was opened. Line at the antenna down end was closed. A
transformer was installed at the antenna. Transformer was made
on to a ferrite ring in dimensions 60x40x10 (ODxIDxH).
It were wound by a twisted wire 8 turns, schematics is shown in
the Figure 1. Antenna had grounding. It was made by
wire in dia 3- mm that was connected
to aluminum tube in 3- meter length that was inserted to the ground.
The antenna could be tuned from 1.8 to 30.0- MHz.

Figure 2 shows MAXI RX3MS Helical antenna.
The antenna was made on the mast in 10- meter length. A dry Pine
Tree Pole was used to make the mast. On top of the mast was installed
a 7- meter long plastic fishing pole. 30 meters of twin wire line
in plastic insulation was wound around the plastic fishing pole.
Line on the antenna end was opened. The same line was downed to
the balcony rail. A transformer was installed at the antenna.
Transformer was made on to a ferrite ring in dimensions 60x40x10
(ODxIDxH). It were wound by a twisted wire 8 turns, schematics
is shown in the Figure 2.
Antenna had grounding. It was made by wire in dia
