Well, that's not quite what I meant - I am sorry if I was unclear.

IIRC, there is nothing at all wrong with burying a cable, and in fact
it helps to keep the RFI away from the run, as well as keeping the
outer braid near the earthen ground and helping to bleed away currents
travelling along the braid. That is what I was asking about - whether
a poly tube would lessen this desirable effect.

I have every intention of grounding the 9:1 unun, presuming it will
enhance performance (if it does not, I'll disconnect it). If
necessary, I'll also install the RF Isolator and try it both grounded
and ungrounded.

I had never heard that it was necessary to keep a solid mechanical
ground water-free, although I guess I can see the value. I don't
understand what vaseline does - just protect against corrosion? I
doubt if it would help the electrical connection.
You're not supposed to use braid for grounds.
