Re: [TowerTalk] followup question on verticals in trees

[Bill Aycock <baycock@direcway.com>]

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
