Receiving Field HF Loop Antenna

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.
