[TowerTalk] Stainless Steel Hose Clamps on antenna elements

[Jack Schuster]

Went up the tower today to look into an intermittent problem on my middle TH6. I had rebuilt it probably 5 years ago, and noticed a couple days ago SWR was way up on all three bands. That  night it was good again. Since the DE can be reached from the tower, I decided to remove it and found FIVE stainless hose clamps that I had used to replace the rusted original hardware very loose! I noticed that although there was no sign of rust, there was no name on these clamps. They were all stainless with 5/16 hex head screws, so I could tighten them  down pretty well and I'm sure I did originally.

Has anyone else experienced SS hose clamps loosening? Is it a matter of the no name brand?    Tnx    JACK W1WEF
