> I am researching a tower and if I have it my way I will be able to put
one up within the next 2 years unless something really inexpensive comes
up in the mean time. The XYL does not want me climbing the beast so
that makes me have to consider a crank up. At present I am thinking of
the US-Towers HDX555. I am trying to fit wants/needs and village
requirements all together so I do not have to pull a PRB-1 act.
The first thing you need is Fred Hopengarten, K1VR's book on Zoning from
Antennas with surface areas exceeding 10 square
feet: antennas and antenna support structures
having a combined surface area greater than 10
square feet or having any single dimension
exceeding 12 feet shall be permitted as an
accessory use if and only if they comply with the
A.Height Limit for Detached Antennas: No
combination of such antenna and antenna
support structure shall, if ground mounted,
exceed 65 feet in height.
The antenna and its
support structure shall be designed to
withstand a wind force of 80 miles per hour
without the use of supporting guy wires.
Setback from Adjacent Buildings: No antenna or
its support structure shall be located in any
required side yard or nearer than one-half of the
height of the antenna and support structure to
any habitable building on any adjacent property.
Well, that some verbiage but every building department has different
regulations even though they might be based on the UBC, IBC, etc.

Probably not true. The vast majority of crank-ups never need cable
> - I might want a fold over
There are a limited number of them.
> - best NOT to climb a crank up unless it is fully collapsed
And safetied with some 2x4's or pipes thru the braces under each
> - I might have to bring it down in stormy weather (Illinois,
McHenry County is an 80 MPH windspeed zone so any antenna structure you put
up will have to meet that rating extended.
> I am new to towers so I will hang out on this list and read the archives
any other suggestions of where to look for information so that I can be
best prepared when I have the money?
Good ideas. I'll guarantee you'll learn LOTS about tower and HF antenna
construction projects. And true north. And which kind of owl works best on
your tower. You know, vital stuff like that.
> I would also like to know if it is
a good idea to hire a contractor or get a bunch of Ham buddies that have
installed towers to come do the job.
Umm, it's hard to screw up an amateur radio tower but it's been done. If
you don't know - ASK! That's why we're here; to help keep people out of
trouble when it comes to tower projects.
OTOH paying a professional to do it is one way to get it done right the
first time. You can participate as little or as much as you want with someone
else worrying about ALL the details. For many folks a good investment.
> Incidentally I also have a walk
out basement so it is going to be hard to get the concrete and the tower
to the back yard.
Nope. That's what a concrete line pump is for. They're not that expensive
unless you've got your heart set on running all the loads back by wheelbarrow
