[R-390] Underground connection sealant/insulation

[Transmaster]

You really do not have to worry about the silicone sealant that has
the acid component the acid dissipate quickly and is gone by the time
silicone finishes curing.  Are you putting in a ground plane for your
antenna?  If so galvanised chicken wire is fantastic, and cheap. bury
it a couple of inches below the grown and forget about it.
