Hiya, Victor --
Well, yes and no. My complaint is that they use cast aluminum in the
first place instead of steel ala Hy-Gain and M2. I did break the ear off the
mast clamp of the first Yaesu rotator I installed so on the second one I was
more careful. That one didn't break but it wouldn't hold the mast so had to
go back and re-tighten it (initial temperature cylcling probably had
something to do with it.) The wind torque forces on medium and large-sized
antenna installations can be tremendous and asking anything mechanical to
hold a round object (mast) with those kind of forces on it is asking a lot.
"Barely past finger tight" won't cut it in any installation that I'm
Don't get me wrong, I like the clam-shell design; it'll take any sized
mast but think that the choice of materials was more of a manufacturing cost
decision. Believe me, as a past National Sales Manager for Amateur Products
for Hy-Gain by Telex, I am acutely aware of manufacturing costs and their
impact on amateur products. I would rather Yaesu had either 1) charged more
for a real live steel clamp or 2) made one available as an optional extra.
