I think you will need a lot of cable to get even to 10nF value. Also coax 
usually has air gaps which will ionise and lower the voltage to maybe just a 
few hundred volts...

For what you may pay on coax you might be better buying some flat sheets of 
plastic to make some flat plate caps instead...

My 2 cents worth.....
