So239/Pl259 are questionable after 3KV.? Been there, tried that.
Don't like the Millen HV because the tip is exposed IIRC.
The SHV works well for moderate voltages but it's not super rugged.? Looks more or less like a BNC variant on the shell. These are harder to get these days as they seem to have fallen out of favor for more modern safety-oriented specialty connectors. But for ham use, they may be what you are needing.
GL!

If you were to 'sing the praises' of those Millen HV connectors, which are
advertised up to 7KV, Shane, WP2ASS, might bop you on the nose! I have used
them to 2KV but I would go much above that because they lack a lot of
protection where the wire goes into the connector itself. I have some SHV
that require RG-58 or a reasonable facsimile thereof. Recently I used
these:
One of the companies that makes a Megger uses it to 10KV. I'm only using it
for 2KV but the bare conductor is buried deep inside the ABS probe so that
it isn't exposed. The only issue I see is that the manufacturer doesn't
state the current. It didn't bother me since I was looking at a max of about
300mA on my modulator. However, YMMV!

Don't depend on haphazard grounding for HV power return, run a
separate dark cable for the HV return in addition to having a common
shack grounding system.
Use bright red HV cables and purpose built HV connectors. Millen HV
connectors have been used in Amateur radio applications for a long
time.

HI all,
Thanks for reading the mail. I have acquired a home brew amp
and power supply that is missing its HV cable. I'd like to change
both
of them to one style since they are both different. Jack Schutt K9GT
originally built this. I'd thought about using SO-239/PL-259's that
are
Teflon with RG-8 inner conductor cable as the HV wire and packing
the PL-259's with RTV-108 and sleeving the wire with GOOD Belden
heavy shrink tube with sealant. Does that sound like it would hold
5 KV since that's what Jack built the power supply too? Thanks
for the input and reading the mail.
