Gene,
The same procedure is used for ground kits: a layer of vinyl over the
parts you may need to uncover in the future (the industry calls it a
*courtesy wrap*), then as much butyl as needed to form a gradual taper
(and put a gob under the ground wire where it leaves the shield), and a
couple layers of 2" vinyl, and a couple layers of 3/4" vinyl. That will
be bomb proof.
No one uses a *mastic pad*, but it can't hurt I guess.

Thanks for the info and especially for the link. I now have it
downloaded into my tower docs on my PC. The Andrew process seems to be for
symmetrical connections but not for the asymmetrical connection to a shield
ground. (There is probably a separate doc for that.) That's why I used the
mastic pad - it could be molded around the odd shapes that comprise the
ground connector and hardware. For my next shield ground (when I install
the replacement cables on my tower), I'll use the Andrew doc and probably
even the Andrew materials along with the mastic pads. Thanks again and HNY.

Gene,
Your latest waterproofing idea is a close clone of the Andrew splicing
process.
one layer of 3/4" 33 or 88
two layers of amalgamating sealant tape (more like butyl than silicone)
one layer of 2" 33 equivalent,, the 2" is important to not squeeze out the
sealant tape
another 3 layers of 3/4" 33 (actually the kits contain 3M Temflex brand, a
cheaper version of 33)
(my tower guy then adds a heavy coat of acrylic clear spray)
The Andrew kits are cheap (<$16 last bought) and have enough for materials
for a dozen UHF splices.
All comes off clean and is proven in commercial service.
