Why are magnetic loops used in amateur 8-shape antennae?

Click For Summary
SUMMARY

The discussion focuses on the use of magnetic loops in amateur 8-shape antennae, highlighting their advantages over S-shape designs. Magnetic loops are preferred due to their compact size and efficiency in signal reception and transmission. The conversation emphasizes that the 8-shape configuration enhances performance in specific frequency ranges, making it a popular choice among amateur radio enthusiasts.

PREREQUISITES
  • Understanding of antenna design principles

Over the literatures there are S-shape and 8-shape antennae been discussed.
What are the differences?

The 8-shape seems to be found in amature using magnetic loop. Why magnetic?
