Default Capacitive loading-How?

Hi,
Anyone have any suggestions on how to physically realize 2500 ohms capacitive
loading on a wire antenna element at 147 mhz? This works out to about .4 pf.
Max voltage will be around 650 Vrms. I am familar with the various ways to
make a capacitor, just can't decide the best way physically to do this. Also,
how about measuring a .4 pf cap. at 147 mhz with an antenna analyzer that only
goes up to 650 ohms? Measure with it stuck at the end of 1/4 wavelength
transmission line? Any suggestions appreciated. Oh, and why do I want to do
this, EDZ beam design I am playing with.
