Antenna Alford 1.2 Ghz ATV
l'Alford entra la risuonare sulla frequenza stabilita 1.240 Mgz, l'antenna e' stata misurata con strumenti adatti per la radio frequenza

Antennas a fentes
Slot antenna and complementary dipole, it is shown that on condition of inverting the E and H fields the slit has the same radiation pattern as the elementary dipole

Slot Antenna
The length of a slot determines the resonant frequency, the width of the slit determines the broad bandwidth of the slot radiator

Corner reflector in microonde
L'antenna Corner Reflector e costituita da un riflettore a V e da un dipolo


Linear-loaded-short-dipole-21mhz

Linear loaded short dipole 21Mhz For my amateur radio activities on the HF bands I only have a 3.6 m wide balcony available for antennas. After some study I decided to experiment with a shortened dipole for the 15 m band
