Magnetic Loop Experiments
A 145MHz 2m loop. Using the software at the bottom of this page, I worked out that a 36cm length of wire, will need a capacitance of around 3.6pf, and around a 50% efficiency
Magnetic loop for 160M
Tuning capacitor and section of 160m-loop 7/8" Cellflex-Cable, 2.8m diameter
Magnetic loop with capacitive load for 30-10M
Equilateral Triangle Loop, Aluminium Profile 8 x 1mm, 1m side length
Portable Magnet Antenne von
An old radio-controlled rotary capacitor approx. 2x350 pF, a rotary capacitor approx. 50 pF for the 10-15 meter band, voltage-resistant ceramic capacitors 500pF to 3500pF
