Log periodic 4 elements


My main limitation being this small mast, I had to make a tough compromise and my 12 elements turned more realistically into a 4 elements design. The 4 elements were calculated to be part of a 8 element design, in case I could build it in future times

Antenna multigamma a L rovesciata
L rovesciata, forse la cenerentola fra le antenne, che pero' ha il pregio di essere di una semplicita estrema meno di cosi'si rinuncia all'antenna

Antenna filare doublet
La Doublet antenna altro non e' che un dipolo multibanda tagliato per la piu' bassa frequenza di lavoro e alimentato al centro da una linea bifilare da 300 Ohm

Antenna on the 1.8 - 10.1 MHz bands
It is known that the best from non-directional DX antennas for communications on the low bands are vertical, having a low zenith angle of radiation. But quarter wave height at 1.8 MHz 39 m

Antenna W3DZZ
The standard version of the Antenna, L - 8.3 uH wound on a frame d - 50 mm. length 8 windings 80 mm. number of turns 19 C = 60 PF. The contour is tuned to the GIR frequency?, 05 MHz

Antenna Windom la multigamma
L'antenna Windom, la quale non e' altro che un dipolo avente una certa lunghezza ed alimentato ad un terzo anziche' a meta. Mi spiego meglio: se noi prendiamo un dipolo lungo meta' lunghezza d'onda che risuona sugli 80 metri e lo alimentiamo al centro con un balun 1:1, avremo come detto la risonanza su tale banda
