Gerald & others:
This issue of lambasting Rohn for not sharing data that they may have is
interesting. From my perspective, if I were Rohn Company, or the owner of
that
company, I would do exactly what they are doing.
Couple of points:
1. It's not their fault that competition doesn't exist for their
products.
2. They are not demanding or requiring ANYONE to buy their
products.
3. They do not have a requirement for purchasers to certify their
intended
use of the product before buying it, and they cannot control
the use
of it either. Just like hand-guns.
3. They do have a solution that will work for booms over 10 feet
long, for
which they do have drawings and data. ie: Rohn 25, 45, 55, etc.
4. Even if they DO have calculations within their company for
longer than
10 foot booms on HDBX towers, there is no requirement for them
to share
that information with ANYONE if they choose to recommend a
different
solution. Ostensibly those calculations could prove that for
95% of
the cases a TH7DX could be mounted on an HDBX in 300 MPH winds,
but
they certainly are within their rights to protect themselves
for that
remaining 5%, or for Marketing reasons for that matter.
5. In this litigeous, lawyer infested, "too many laws" society
that we live
in--in the USA, Rohn is very WISE to not share any information
with
anyone. You can bet you boots that they would get sued if they
did
share information and SOMETHING unpleasant happened because of
doing so.
6. The guys that Stan W7NI referred to who had BX towers buckle
with TH6
antennas on them have empirically shown that a TH6 type antenna
is
too big. Rohn recommended AGAINST putting that big a beam on
that tower.
Rohn is clean.....no freaking lawsuits.....GOOD ! The hams
with those
broken tower & antenna installations tried to go forth "on the
cheap",
against guidelines from Rohn. Now, they can abide by Rohn's
guidelines
(and not exceed 10 ft boom lengths), or they can buy a tower
that is
recommended for their installation, or maybe they can get an
insurance company to replace the crumpled one.
I'm surprised to see all the negative barbs thrown toward Rohn for protecting
themselves in a society that circles like buzzards to sue the guy next door.
Good for Rohn!!
For what it's worth, I have NOTHING to do with Rohn company. I have
purchased
their products in the past though,
