Les Loop en LF et VLF
Thus for F = 136kHz wavelength 2205m if the parasite is less than 110m, its magnetic field will be more than 10 dB below its electric field

Loop magnetico per ricevere le ELF
I wrapped about 1710m of 0.50 mm diametrp painted wire in a one meter octoloop
Loop 4 m octagonal perimeter 14 MHz
On my list of new antennas to experiment with is a magnetic loop with a broadband current amplifier in lieu of the usual resonating components
Antenne a telaio
Framed antennas We all had a disappointment when we tried to connect one of those vintage frame antennas to a home radio
Loop Antenna Remote Tuning
Draw a 36-inch diameter circle on your garage floor. Lay a yard stick across the circle with one edge on the center

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
Interface-for-digital-broadcasts-with-integrated-audio 4-port HUB, with a TUSB2046. With port 1 of the HUB we drive the FT232RL; with port 2 the PCM2904, furthermore, we decided to leave ports 3 and 4 free
