Low loss wire traps 12 & 17m
Wire traps do exhibit a high Q-factor so are in theory less lossy compared to coax traps, but are NOT SUITED for high power 200w

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

50MHz to 28MHz RX Converter The concept of the rx converter is quite simple and nothing really new. the local oscillator is a standard colpitts crystal oscillator producing the 22mhz lo signal
