3 element yagi for 11meter, I1WQR
Antenna with control swr system Harpin gamma match
Yagi due progetti per gli 11m
Yagi 4 elements for 27 MHz
Dipolo filare con balun per 27 mHz
dipole centering on channel 20 CB or 27.205 mHz and using a 4 mm copper braid, from the above mentioned formula we get 150 x 0.965 / 27.205 = 5.32 meters
Hentenna freq 27.500
Hentanna is that if it is mounted horizontally, the resulting RF field is vertically polarized and vice versa
Antenna Stealth Vertical Dipole

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
