RG-213 has a non-contaminating jacket, not a direct burial jacket.  As
I recall it is practically identical to one of the RG-8 versions and I
would expect that the loss figures are identical.  In this respect, I
am referring to what was once a MIL-spec cable, but the term "RG-8" is
now applied to quite a few other cables in the .405 diameter class (as
is also the case with RG-6, RG-58 and RG-59, etc.)

One would hope that vendors who change the design also change the stock
numbers.  Oh, well....
