On both of my 40 2-CDs, I added two stainless steel rivets at each element
joint and aluminum rivets to the boom joints.  I put them in on different,  90
DEG rotated planes.  That is, one rivet pointed "down", the other pointed
"horizontal".  I allowed 3 inch spacing between rivet planes.  I used 1/8  inch
dia. rivets for the elements and 1/4 inch dia. rivets in the boom. For each,
the rivet pull depended on the amount of material into which the rivet was
installed.

I do this on all of my antennas.
