Which of the following is NOT listed as a guy rod size?

In guy rod size listings, the length and diameter are paired so that longer rods use a proportionally larger diameter to maintain strength. The valid pairings shown—12m with 5/8 inch, 18m with 3/4 inch, and 32m with 1 1/4 inch—all follow this pattern. The combination 24m with 1/2 inch would be a longer rod but with a thinner diameter, which doesn’t fit the usual catalog of sizes. That mismatch is why 24m - 1/2 is not listed.
