The reason Tulip Poplars are prone to lightening is because they are
generally the highest thing around. The one next to my barn/shack is now
110 feet tall and dwarfs my 80 foot towers. It does a nice job of holding
up a 75 meter delta loop tho. That tree was one of the main reasons I
bought this piece of property. 73 bob de w9ge

Subject: Re: [TowerTalk] followup question on verticals in trees
Tulip Poplars are very prevalent in my area; I have hundreds. Locally
they are logged for lumber for furniture frames, and shipped to the North
Carolina Furniture factories..
I see one drawback to the Poplar as antenna supports; They are prone to
lightning strikes. I have many with evidence of "hits". After a lightning
strike, the tree will frequently fork above the hit, or develop an "S"
shaped growth pattern. There is also, frequently, a strip of bark that
has been peeled off by the heat from the strike.
Your area may not be as prone to lightning as ours, so this may not be a
problem.
Good luck- Bill

Thanks all for the responses on verticals in woods/trees. I haven't read
or
responded to them all yet, but plan to.
Meantime, I have a followup question that's occurred to me, another
practical, simple, real world kind of question.
I have some trees in the woods that I am hoping are at least 130' so that
I
can put up fullsize 160M verticals without having them slope. If it turns
out they're only 110' or 120', so that I have to have them slope some, how
undesirable is that? How much do you expect the performance will suffer?
What if the trees are only 90' or 100'? (Although I do think the trees
are
at least 110'). Note: the tallest trees we have here in Maryland are
"tulip poplars," also called, I think, "tulip trees," that according to
the
tree book can get to be 150', and I think I have seen some that big over
near the Severn River (at K3HQ's 30-acre place) -- and I measured the ones
at my old place as 120' (by climbing my 160' tower 'til the treetops were
at
eye level and gauging it that way). These trees have a "habit" of being
"columnar," and I have noticed they do this when they are growing amongst
other trees. A tulip poplar growing by itself in the middle of a field
tends to become rounder, not as "columnar" and straight, not as tall.
They
aggressively grow tall to get up to the canopy top and get sunlight.
