CRITICIZE others post an not a positive output
My comments weren't intended as criticism.. Just as another viewpoint.
I was pointing a few possible problems to show to others what can happen
or give another possibility
to do not put in risk life or property but what was the response?
supportive? destructive?
Indeed.. but one aspect that comes up a LOT on TT is the whole thing of
"code compliance" or "good engineering practice". Whether it's guying,
strength of materials, or grounding practices, there's a huge amount of
room to maneuver, depending on what one's risk acceptance strategy is.
I think that the original topic here was an excellent example of someone
who has a situation where "if it falls down, nobody will care, other
than the builder", which is decidedly not the case when the local
planning department is asking for wet stamped drawings from a PE (or
maybe it is, and asking for excessive documentation is a way to restrict
antennas and towers).
I didn't see anything fundamentally "unsafe" in the pictures. Unlike a
lot of field day pictures you see, there's nobody standing underneath
the towers being pulled up, so if his manky tow rope does fail, he winds
up with some bent scrap metal, not a trip to the ER or a call to the
coroner.
One can be "over-cautious" ( I think that characterizes much of what I
do at JPL.. we are definitely risk-averse), and the most useful
discussions on TT are where one finds out where one can do something
that is "not the optimum".
And a lot we do in ham radio, as a matter of course, is not
"code-compliant" and that's hopefully done with an appreciation of the
risks being taken.
I'll bet very few people with wire antennas follow all the electrical
code requirements (copper clad steel, AWG12, etc), but one hopes that
they realize the trade they are making: the antenna might come down in a
strong wind or when a big bird lands on it; and if it does, hopefully
they've situated it so that it doesn't wrap around the local 14.4kV
medium voltage feeder. And if it does, hopefully, they've got a decent
protective unit bonded to the safety ground system.
If this ham owns all AZ, not a close neighbor and his tower fall and
kill him , his dog or his wife and safety advice before can be good?
I think, based on the pictures, that he does have that appreciation.
your comments are well taken, but I think have been addressed by the ham
in question.
I was thinking this reflector was to HELP others to make good or right
things, to avoid problems
or save some time and money and keep them ALIVE not just to criticize
with no positive output
Criticize is good but giving a better result or to fix others wrong doing
My intention is not to start a war, just share my point and no intention
to offend others with my words, if for some reason are crude
possible is the result the spanish to english translation process in my
brain
but I try to share and help and give my opinion with the intention to help.

Well, if you're raising it in your (big) backyard, and you're aware of
the risks, then you can use dental floss if you think it will work.

That would be a problem.. Maybe his "200 foot" tower is actually 199
ft, 6", and exempt.

I'm thinking some sort of shock absorption.

if the guy doesn't happen to be "the wrong length", then there's no
particular reason for insulators (unless you're feeding the tower as the
radiator)
