The Nicopress sleeves are certainly superior, but typically require the addition of a turnbuckle for length adjustment. With the Phillystran, use the 4000# size with Big Grip ends, a turnbuckle, and a thimble for a boom truss.

Over the years, it seems that most antenna manufacturers have moved to using 
some form
of Nylock nuts (the nuts with the nylon insert for "high vibration" 
applications).

I have seen this on my Cushcraft XM series monobanders, on my Optibeams, and 
most recently
on my SteppIR (DB36).

With respect to the latter, the cable clips just use a single nut to compress 
down on the wire
cable. There is no locking nut, no lock washer, no Nylock, etc.

Why is this?  I have heard from others that this can be, and has been, a point 
of failure.

What method would you suggest to ensure that these wire rope clamps do not 
loosen up over time?  Just electrical tape?
