RG-500 coax setup

[Lazy_Asparagus92]

Is Teflon RG-500 coax a good choice between a 2500 pF vacuum cap and dual Jennings output relays? I'm also using RG-200 for the bypass and added a spark gap across the cap. Thoughts or suggestions?

The RG-500 is a great choice for high voltage RF applications. If you're looking for improved power handling between your vacuum cap and relays, you might want to look into RG-393. Also, make sure to maintain the right spark gap spacing to ensure protection

Spark gap helps protect the cap, just make sure it's tuned and keep the leads short to minimize inductance.

You might want to double-check that the Teflon RG-500 can handle the voltage and pulse from the 2500 pF cap and dual Jennings relays without breakdown.
