A major manufacturer of wooden poles is McFarland.
Their site has a Pole request form, that you specify everything, including
delivery means, and they deliver a quote.
Indeed some city QTH's could not be a destination for a 120 footer, as
mentioned. McFarland Quoted me a Class 1, (thick) 120 ft pressure treated
pole, delivered to the property line, horizontal. They handled all the
reconaissance, permits, chase trucks, and logistics of transport of the pole
to the property from their yard in Idaho. The 10,000 lb pole cost at the mill
in Idaho $3500. Transport to my yard, (Monterey area) was quoted $4000.
I did not solve for the costs of drilling the hole, (no concrete necessary) for
this theoretical exercise. The required depth was quoted to me as being 10
percent of height + 2 ft..... Hmm 14 ft sounds shallow for 120ft..er 106 ft
Or the substantial cost of man-machine handling of the horizontal pole into the
vertical position in the hole. Let's say hole drilling and erection costs $4K.
Add step hole drilling, (not expensive if done in Idaho + $2 per step, say
Add hardware to clamp to pole to support rotors and thrust bearings, etc.
I will guess $600 for that and we have ~$14,000 for a 120ft self supporting
VERY HEAVY DUTY mast. I dont know what that compares to a self supporting
metal tower, or a 120 ft guyed tower, but would be interested in knowing how
I will get a copy of the article...BTW, I wrote for CQ recently, and learned
that their copyrights are one time, for the period cycle of production, after
which they are perfectly OK with putting their articles up on the web. So
check with them directly to confirm whether you can post digital copies on the
web 30 (or 60) days after publication.
