I've never really had problems with good quality RG213/U, just burying it
without additional protection; however, not having any problems doesn't mean
it's the right thing to do. In my amateur installations, where if I needed
to, I could replace runs of coax in less than an hour on almost any antenna,
I don't worry about it very much. In a severe or difficult to access
environment, I'd worry more, and probably use the correct products.
