Long wire con balun 9.1
Ho utilizzato circa 15 metri difilo elettrico da 2,5 mm di Ø, steso fino ad un isolatore

Wire & Random Antenna Links →
My Antenna Zepp, Double Zepp, or Dipole
Two independant wires separated by insulated spacers and usually having an impedance in the range of 400 to 600 Ohms
Reversible Parallel Slot Antenna
Low Profile Paired Verticals for HF a couple of years back and I decided to build one for the low end of 20 Meters
Simple wire dipoles and verticals
You can achieve the bang of a horizontal dipole at a one half wavelength height required for low angle DX performance
Sky-Hook for the Antenna Wire, DL6IP
The receiving antenna was a 122m long wire fixed to a Kluever Kite that served as a sky-hook. This law of physics is still true today

PIC-Keyer This project describes the construction of a real "QRP" keyer with a small microcontroller PIC 16F84, with slightly modified hardware also PIC16F62
Qrm Eliminetor The principle is based on the fact that the interfering signal from the main antenna coming from the local interfering signal is phase-shifted by means of an auxiliary antenna so superimposed that eliminate the interference
