What you failed to mention is that gravity is what really holds the
DB-224 together. The two sections slide inside of one another. Exactly
the same as a Rohn tower section. The hose clamps are to simply keep
the sections from moving at the joint.
I've installed countless numbers of them (and the UHF version DB-408,
DB-411 etc) on commercial towers. They work and hold together just
fine. They can even be lifted by the top and they hold together just fine.

rivets on the smaller sections. Not a failure since. I've
mostly given up on hose clamps as a reliable antenna fastener.
