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.

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
