Kalypso RX HF Loop

This is an early project for a tactical RX loop over all 40 meters HAM band. No need adjustable high voltage capacitor. Only need about 2 meters foam -75 ohms, vf:0,82- coax and a fixed 150 pF capacitor (ceramic type, low voltage -remember.. RX antenna only!).

Emergency style, simple and easy to make, but amazing performance. Try yourself!

This are some model draws:

The schemma:

And two photographs tunna-tin made style. 80 meters prototype:

20, 40 and 80 prototype:
