[BC] Electrical Code, drift to towers

[Jerry Mathis]

I've heard much to the contrary over the years. It started with a consultant 
who did field strength measurements based on the seasons and what results 
were desired (low or high readings). Seems like I've read, although I can't 
quote it at this time, that trees, especially close in, absorbed a 
significant amount of an AM signal.
