Thanks to every one for the valuable information and comments. It was very
constructive and my seamanship sail will benefit from all those inputs.

Denis,

As the coax is more a shielded cable than a transmission line, do your
best to put the conductors together and forget about it.

I did work in the long lines part of the telephone company many decades
ago and learned how to do a splice in coax. Fortunately, you don't need
to do this.

the simplied version:
- heat shrink 12 D long on the cable
- strip the jacket back 5 D - both ends
- fold the shield back over the the jacket
- cut 10D of doner cable for working material and pull it apart
- strip the core insulation 3D
- join the center conductors as specified
(for your little cable - wind and solder the conductors)
- take core insulation from the doner and cut a piece about 10% too long
to split and place over the conductor splice.
... if you can not make it close-
cut a sliver of insulation to plug the gap
- wrap this insulation with tape to completely seal the cuts in teh
insulation
- pull the shield braids back over the splice
- trim shield braid to 2D overlap
- wrap shield with stands from the doner as required for smooth joint
- solder the shield (enough so it makes contection will do for you)
- slide the heat shink and heat as required

This is only about a hundredor so lines short of the instructions I was
given so many decades gone.

It looks like I may have to replace the coupler for my Loran C to make
it
work.
Failing to get a new one I have locate an old coupler that work. The
couplers appears to be sealed and the connections embedded. So I will
have
to cut the coaxial at the coupler and re-route new cable. As the
connection
will be outside I hate to use cable to cable connectors. May be there
is a
way to make a nice splice using braided sleeve. I would appreciate any
instruction on how to do it.
