There’s a joke in the world of radio that all you need for a HF antenna is a piece of wet string, but the truth is that rudimentary antennas rarely perform well. Random pieces of wire may pull ...
Magnetic loop antennas are great if you are limited on space since they are just a potentially small loop of wire. The problem is, they are sharply tuned. You normally have an adjustment capacitor ...
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 ...
This report discusses the use of loop and ferrite rod antennas at HF, and presents both theoretical and practical results.
Shielded Loop Antennas for the AM Band Mar 8, 2013 5:01 PM, By Doug Irwin CPBE DRB AMD Last month I wrote some about making a notch filter for the AM band. However, before you have any signals to ...
