I don´t have line of sight. The nodes are not at the same level. The site is a garden and the second node is on a lower step, inside an utility room. The difference in height between them is about 6~8m. Is it possible that this is causing the bad communication?
I was not predicting this problem, the distance on site is really bellow the 300m.
Can you send me some links for antennas? I can only find 433MHz with 3dBi or less...
