Hi Bob,

Yes, it tends to get better later on.  My only guess at this point is that 
the humidity goes up in the fall (we're very dry here in the summer), but 
the leaves haven't actually fallen yet.  So, that could raise the path loss 
for a while until the leaves actually drop.

On the other hand, a lot of the trees around here are evergreen, and I don't 
see a problem in the spring when the leaves come out but before it gets 
really dry.  Nor does there seem to be a correlation with rain or fog.  It's 
not a big enough problem to invest a lot of time or money on, just a 
curiosity.  (For other reasons, however, when the cable guys come through 
with their Internet service, I'm jumping!)

Interesting.  No, I have no clue, and my data is only empirical.  I hope my 
link still gets bettere as more leaves fall...


Hi Bob, Joe,

This is very interesting; I have the reverse situation.  My home internet
connection is from a wireless ISP who uses 2.4 ghz 802.11b Wi-Fi equipment.
The run from my house to his central antenna is about 3/4 mile, with a gain
omni on his end, and a grill on mine.  There are a few trees that we're
shooting through, trunks mostly, aiming between the fluffy stuff.  I've had
this setup for several years now, and by far most of my problems with
service are in the fall.  Rain is not a factor (it doesn't really start
raining much here until winter sets in).  Not the leaves (they're falling
not growing).  Not anything I can put my finger on.  I'd love to understand
why.  Any ideas?
