Hose clamps come in different widths, materials and styles. I am not sure
what MFJ/ Cushcraft uses or what failed for K6UJ, but on my homebrew
antennas I use worm drive hose clamps with a 9/16" wide band and a 300
series stainless steel screw. For 1 1/4 or larger tubing I use a bolt style
hose clamp.

Doug,
I no longer use hose clamps after having them strip as you had happen or the
connection
loosening after flexing back and forth in the wind (I am also in the Pacific
NW)
Now I only use rivets. I have had a number of Force 12 antennas and no
problem
at all with the connections. Their riveted conns sold me. The HF beams I
have
fabbed have riveted elements
and no problems. I wipe on Penetrox when assembling and later when taking
apart
the tubing is like new. Plus to change element lengths it is super easy to
drill
out the center of the rivets, they pop right out. Now I can sleep easy
while
the winds blow, hihi.
73,
Bob
K6UJ
