Hi -

I wonder if someone has any experiences on tree attenuation caused by 
jungle trees on short waves below 30 MHz for horizontal antennas. I 
googled a bit but without too much success because most of the 
informations are relative to higher bands.

Actually, we are planning to add a new tower in our contest QTH which 
might not be located in a clear environment, especially for the Europe 
path where there is a small but dense forest (500-meter long) in the 
near field. Trees are about 15-meter high but the tower and antennas 
will be well above. You can have an idea on the trees with this picture:

How important could be the attenuation?

Thanks in anticipation
