[edit] HF multi-turn loop

Multi-turn loops are typically only used for receiving, as the signal radiating from neighboring turns tend to cancel somewhat when transmitting, reducing efficiency of the antenna. However, if you want a good receive antenna in a very small space, multi-turn loops are a good solution.

  • Ferrite loopstick]
  • Long loopstick (may work for transmit)
  • Air core large diameter multiturn loop

[edit] slinky HF

Local comments about slinky antennas:

  • Works like a broadside helical
  • Very portable
  • Unstable for fixed use -- wrap your own with copper wire around PVC instead

These links are still being checked...

For use with tuners and loops.
