Multiband short dipole construction
The multiband short balcony dipole is finished. It's 2 meters long, has large capacity hats, requires no ground plane, and can be tuned, by tapping coils, for perfect SWR on 40m, 30m, and 20m

Jar Capacitance Calculator For Coils
The purpose of the calculator is to determine the capacitance value of the jar capacitor needed for the circuit's coil
Le mie sloper per 80/160 Lunghe solo MT. 17,50
Ho fatto una trappola per gli 80mt con del filo di 2 mm avvolgendo 40 spire su un diam. di 50 mm
La nobile arte di costruire le trapple hf
La descrizione della costruzione della trappola e' anche lo spunto per divulgare alcune astuzie che molti OM sanno, per esperienza, e che si tramandano verbalmente
Coaxial Traps
The Coax trap program computes design parameters for the construction of coaxial
Linearly-loaded dipole traps 80-40-30m
For tuning of the traps for this project with MFJ antenna analyzer is util a though
