Trappole per dipoli
Io ho realizzato un programma chiamato Trap che, con metodo iterativo ma molto rapidamente, sintetizza il filtro, ne calcola il numero di spire e verifica la frequenza di risonanza

Tuning HF Coaxial Antenna Traps
Studiare un sistema accoppiato d'antenne mi sono imbattuto nell'arcinoto modo di tagliare un coassiale esattamente lambda/4

Quick Trapped 15/20m Dipole
The traps were tested using a coupling loop to the homebrew antenna sweeper and with a little squeezing, they tuned to 21.1 MHz

Variable Inductor Design
I have been looking at the typical roller inductor used in antenna tuners and some amplifiers and I have come up with what I think is a better design
