Super Penetrator ground radials replacement tubing sizes?

[gridsquareguy]

got this old Super Penetrator antenna, been sitting around doing nothing for ages. 2 of the ground radials are bent all out of shape and rusty. Has anyone ever swapped these out? Also trying to figure out what size tubing works best

Yep, I've swapped mine out before. 3/8" aluminum tubing worked fine for replacements, just make sure the length matches the originals and if the threads are still good, you might be able to reuse the base fittings too
