In the early days C3, EF 180B, and 240 generally used 0.125 inch rivets
on the elements. The 180B had some 0.25 inch rivets as well if I recall.
Booms used 0.25 inch rivets. The C3, for example, generally had 3 rivets
per joint in the elements. I don't know how different the XR series is.

I understand the new antennas use 2 sets of opposing blind rivets.
