Cut down your path loss

Here is a repost from a wireless networking forum that shows the impact of a single small tree in the line of sight at 5.8 GHz

The antenna is at 35 feet above the ground. I'm 250 feet from the antenna.

LOS signal was -68 dBm. With the tree in the way, it was -78 dBm. That's a 10 dB difference, or a ten times reduction of signal.
