[Antennas] Splicing Coax

[Jan Reimers]

Any body have any tips/tricks for splicing coax (for example RG213 or RG8/U)
rather than using connecters/unions?

I was thinking of 
1) removing half the center conductor strands on each side and soldering
them together.  
2) slip on a sliced piece of insulator over the joint.  
3) somehow fudge the braid back on top.  (how to solder without damagaing
the insultor material?)
4) Perhaps seal with heat shrink tubing.

usage would be VHF and below.

Why do I want to do this?
1) I am always running out of PL259's
2) A good splice should be less lossy than a 259-barrel-259 junction.

Thanks
