Antennas for the New Beacon Design
The new 3496 class-E high efficiency Beacon design
Bandpass receiving loops for 136kHz and 500kHz
I designed receiving loop antennas with a bandpass characteristic to cover the whole 136kHz band without the need for remote tuning
Broadband magnetic active antenna
I have built a broadband magnetic receiving antenna. The hardware is ready in a first expansion state
Build a simple magnetic loop antenna
For the main loop I used a soft copper tube, diameter is 10 mm, length about 3 meter. The smaller loop is about 60 cm in length diameter 1/5 of the main loop, material is 1,5 square mm copperwire
