wow, this sounds a little over the top. I can sort of understand why they
want soil sample studies, because they want to insure the soil can support
the tower etc...I assume it's an unguuyed tower...but an environmental
impact study is quite a stretch.
that would be like a gas station asking for an environmental impact study
when they sell you gas for your car lol.
kind of doesn't make sense from a business perspective.

>> Hello list,
>>
>>
>>
>> Has anyone on the list looked into Luso towers when shopping for a new
>> one?
>> For those that aren't aware of Luso, it is a Japanese tower builder of
>> heavy
>> duty electrically operated crankup towers in heights from 90 feet to over
>> 300 feet. They accommodate antenna, rotor, and mast weight of up to 2200
>> pounds. The 150 foot model is rated to accommodate 140 square foot of
>> antenna, and goes from a fully retracted height of 42 feet to a fully
>> extended height of 145 feet in 29 seconds. Masts of up to 8.6 inch
>> diameters are accommodated with multiple thrust bearings. Each model is
>> available with a number of options, including a rotating base, and
>> automatic
>> retraction when winds exceed a preset level. The 150 foot model weighs
>> 29700 pounds excluding options.
>>
>>
>>
>> A friend just took delivery of the 90 foot model with the rotating base
