The capacitance per ft and simple arithmetic will get you a DC capacitance value that is reliable but add in frequency of the applied voltage and inductance rears its head. As per others, you get a stub, not an idealized capacitor.

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.

Sure.. 25 pF/ft, so 6 ft.
