Jay,

I found my PAØRDT probe is a good tree detector.  It works great just 
ten feet above ground out in the open field in front of the house.  With 
large oak trees all around the house with it as much as 40 feet above 
ground the probe doesn't work near as well as a loop.  And that's with 
it about 40 feet away from the nearest trees that are about the same 
height as your trees.  I thought about mounting the probe at the top of 
my tower but it would have to be below the 6 meter J-pole lightning rod 
to survive.  My neighbor has a good view of my towers and he has seen 
many direct hits.  Molten balls of copper on the copper pipe cap top 
confirms the strikes.

I bought enough chain link fence top rail sections last year to attempt 
pushing the probe out the top of a pine tree about one hundred feet from 
the shack.  My idea was to attach a ten foot section of PVC pipe to the 
tree trunk as high as my twenty foot extension ladder would allow.  Then 
devise a rope and pulley hoisting contraption to raise the mast sections 
one by one up thought the PVC pipe.  The tree I selected has lots of 
branches near the top that I believe would keep the mast upright.  Guess 
I better do this while I can still run :)
