Hi,

BombayBill:

The antenna now sits about 22 m above the ground. It now has a slightly better line of sight through trees and over rooftops to 3 sensors sitting within metal waste bins at distances as much as 1.4 k away.

This reminds me that when it comes to through-forest communication I have observed that a transmitter should be below 1 meter or above aproximately 6 meters to prevent “blocking” by bushes and low vegitation. I observed this at a HAM-camp where I delivered WiFi access to a large group of campers.
