I have an old (bought new in 1975) Heights 72 ft (18 sq ft rating) on a
4 ft tilt base and don't have the "clanging" sound that you are talking
about. Wonder about the "fit" from section to section. The sound may be a
result of the torque as the tower twists in the wind. It almost sounds as
if you have some bad welds.
I'm not sure that you can do anything about it in the air. But, next
time you tilt it over, take the antenna off, and try twisting the tower from
the top section. See if you can identify where the sound is coming from.
Just a thought.

Subject: [TowerTalk] Heights "Clanging" noise at moderate winds
New to the list, but have done some reading of archives.
I bought a brand new Heights Tower, 72' plus the tilt over 4' base, 25 sf
wind load. I had some issues with this "clanging" sound when I had it
assembled, but without the bean, a Force 12 C4. Drake, Heights owner,
thought that I may not of had the bolts tight. I bought a high grade torque
wrench and made sure they were set to the setting he suggested. I finished
my installation, adding the antenna and cables, and raised it back up. The
winds were calm and all was quiet. A couple of days later we have moderate
winds of 15 mph, and the tower sounds like there are a dozen people hanging
from it with wrenches clanging at every joint on it. When the wind is
low...few sounds, when the wind picks up, the clanging picks up. Directly
related to the wind on the tower.
If somebody has had the same issue with this tower, what was the solution? I
have invested nearly $10,000 on this tower, which is a huge sum of money for
me (over 2 years of savings), but thought it would be worth it. I have had
aluminum towers in the past (Universal) and never had this "clanging". I
live in a residential area and am concerned more about the noise than
anything. I will have to lay it back down till I find a fix. NOT a happy
person.
Any suggestions, GREATLY appreciated.
