I’d love to build a magnetic loop antenna. The bulk of the construction is easy to do. The main killer is the capacitors. Vacuum varicaps are hugely expensive and you have to be very careful ...

Paper 403: Measuring magnetic loop antenna performance. Despite the advent of the internet and streamed services, there is still an interest in traditional broadcasting. With that interest comes a ...

An accurately calibrated and sensitive antenna is needed for such work. This White Paper looks at the characterisation of magnetic loop antennas — those sensitive to the magnetic component of an ...

Fig. 1 illustrates the nightly coincidence of micropulsations, measured with a 6-ft. diameter magnetic north axis loop antenna of 21,586 turns and 3914-Å. auroral pulsations from 70° of sky ...
