Hi Eduardo,

I have been using this type of coax loop that Pete describes with good results. I believe the key is to place it as far from the TX antenna as possible, and if possible make sure the null is in the direction of the TX antenna. In my case it does improve signal to noise ratio compared to my inverted L. 

But an even better choice is a Pennant, Flag or, if you have the real estate, a Beverage. I find the pennant the best compromise. It is easy to construct and deploy, and it has good F/B ratio. I use two pennants, one pointing NE for Asia and the other NW for NA. 

I am still using my 20 ft coax loop as a diversity antenna facing NW/SE which make the whole setup suitable for both DXing and contesting.

Here is K3KY's useful collection of flags and pennants stuff;
