- A magnetic loop antenna for HF
- Able to cover all frequencies between 3.5 and about 10 MHz, the loop described here is directional, does not require a radial system, and stands just 1.8 metres tall. Most parts needed can be purchased at a hardware shop. The antenna can be put together in an afternoon and requires only hand tools to assemble. It should cost less than sixty dollars to build.

- Magnetic Loop antenna
- Why is an Magnetic Loop antenna so special, this antenna is picking only the magnetic part of the elektro magnetic radio wave. The big advantage of this antenna is that the electric interference from the big city have no influence on the received signal
- Portable Loop Antenna
- This loop it is small and light enough to carry while operating, it disassembles into small but rugged pieces that fit easily in a backpack or gym bag, and it can be tuned from 14 MHz to 30 MHz.
This tunable magnetic loop antenna is my contribution to the well established art of amateur loop making. Can be tuned from 14 MHz to 30 MHz.
