Filipe,

My first real gain antenna on 160M was two "T" verticals 
suspended by two wooden poles (could have been trees). 
Spaced 1/8 wavelength and fed 180 degrees out of phase 
(much like the old 8JK design) Easy to feed and had about 
4 dB gain (bidirectional) I worked my first Zone 16 from 
California in 1989 with it. With phasing of 135 degrees it 
would have front-to-back but is harder to feed.

Good luck!
