Dear Charlie AD5TH:
You have performed a great service by presenting the results of K5HGR's
engineering and your work. Its educational value is almost beyond
calculation.

In this part of the world one would need to have a licensed professional
engineer (PE) sign off on such a structure. Clearly, down your way one has
freedom to innovate without concern for issues that we are required to
consider.

My goodness. I recently completed a task of a tall tower in a populated
area where I had to have design work from the factory's PE, have that work
reviewed by a local PE, get permission from the local municipality, have
the airport sign off on the height, take soil samples so that a safe
foundation could be designed, watch the fabrication of the foundation to
make sure that it was done right, and on and on... Course, we do get
serious wind up here and it just would not do to kill someone with a tower
collapse.

You sure are fortunate not to have all of the things we have to put up
with and not even have to worry about wind. Do keep us posted. The whole
story has yet to be revealed.

Charlie,

It's very obvious a lot of hard work went into that project, this makes
it even harder to face criticism, but don't lose sight of the fact that
it's constructive (even though it's deteriorating rapidly.) There really
are numerous problems with your installation, and some will inevitably
lead to catastrophic failure and potential loss of life.

Be careful around that thing until you can fix it up. In the least,
install dedicated anchor points set in a sizeable concrete base, shorten
your top mast and get a thrust bearing up there. Put at least 1/3 of
your rotatable mast below the bearing.

This is by no means a complete list, but I think the majority of readers
will agree it's a good place to start.

Well considering he is the former AB7SL it wouldnt surprise me this is
his creation. If you do a net search on good ole charlie you will find
lots of things. Including his imitating a couple of amateurs on the
newsgroups to promote his spamming of the Newsgroups with the Antenna
sales. I understand that 2 of them were really unhappy about that and
were getting lawyers and soon after that charles disappeared from the
net as AB7SL and now he has reappeared.

Charles charles, when you going to learn.

Hi Mac,
We had certain constraints to work around such as available guy anchors
vs. distance of tower from shack since it is a VHF installation I needed to
be as close to the shack as possible for transmission line loss
considerations even with 9914. Even though we have over 40 acres the tower
needed to be close as hardline was not an option.

I am in the country here so there is little building regulation to adhere to
or approvals of construction projects.

We could and still might add concreted guy anchors although they would give
more interference for the mower and foot traffic in the back and front yards
and that was a concern of the xyl.

The tower has a very low wind load on it with those 2 small lightweight VHF
antennas. I know it is very common for hams to overload their "properly
engineered and maintained " towers.

As far as mating 2 different brands of towers I was on a budget and had
access to 45ft of what has been called "Sears" brand and 40 ft of 25g. We
altered our design from an 85ft erection down to 75ft as a safety precaution
during and after the installation. Yes trees do sway but as the photos
show they don't sway where the guys are attached.

Our insurance man has added the structure to our list of covered items in
our policy so evidently it was OK for coverage.
I suppose that no matter how we installed this tower and I so naively
posted a photo link there are some that will berate it.

TY for your civility however..seriously it was quite refreshing.....
