The
coupling loop of the antenna has diameter 1/5 from the diameter
of the main Loop. It made of a copper wire in diameter near 1.5-
mm (15- AWG). Coupling loop through a small length of a thin coaxial
cable is turn on the DEGEN- 1103. Plastic box from a Chupa-
Chups is protected the soldering of
the coaxial cable to the coupling loop.
Antenna
was tested with the DEGEN- 1103. The antenna works perfect compare
to the small sizes. Loop Antenna works much better the whip of
the receiver. Reception of the Ham- bands and broadcasting stations
was much better compare to the receiver's whip antenna. Figure 2
shows S- meter of the receiver with the whip antenna. Figure 3 shows the S- meter of the
receiver with the Loop antenna. For the test it was used a broadcasting
station working on the 15.300- kHz. However, the loop antenna
loses 1... 2 balls to an internal wire antenna.

Figure 4 shows the Loop Antenna
and the DEGEN- 1103.
Then
the Loop Antenna and the DEGEN- 1103 were prepared for a field
test. Figure 5
shows the kit. Antenna was tested with the DEGEN- 1103 in a field.
Figure 6
shows the Loop Antenna and the DEGEN- 1103 in a field. Antenna
worked fine. I was very satisfied of the work. On my opinion
it is optimal antenna when you want to use receiver in the field
conditions or at hotel room. The antenna as well is good for the
city conditions because it allows eliminate the industrial interferences.
