Reasonably-priced capacitors for traps

Good morning, Bryan.
I have done some reading on coax traps, and consulted with some who, as
the old saying goes, have probably forgotten more than I will ever know
about antennas, and I'm told they tend to be fairly lossy and inefficient.
They are certainly easier and cheaper to build than the coil-and-capacitor
type. The big thing that concerns me about coax traps is that they need to
be fairly small and portable, meaning I'd probably make them out of RG-58,
and I wondered if RG-58 or even RG-8X would handle the voltage.
For ceramic and mica transmitting capacitors, you might try the surplus
vendors.
Thanks. Fair Radio looks like they have a pretty good selection.
