Seems that if you need a value that would require a length that might begin to
look like a transmission line stub, you could cut it into shorter sections and
parallel them.-Mike-WA6ZTY

Yes, rg58 should be about 40pf/ft. just beware, if the length becomes a
significant fraction of a wavelength then you have to calculate the
impedance based on the length and velocity factor.

Hi All
This might seem like a silly question, but is it possible to make a 150pf
capacitor out of RG-58? Thanks and I need one for an EFHW I am building.
