Topband: Capacitors for Antennas

[AD5VJ Bob]

I am reading about the CCD antennas and they are talking about the caps that go into making them, but they are talking theory and
formulas (which is fine) but what are these antenna caps named so I can start looking for some and where is the best place (price)
to find them. What voltage cap is used in an antenna like this.

Luke 14:28-30    

 28"Suppose one of you wants to build a tower. Will he not first sit down and estimate the cost to see if he has enough money to
complete it? 29For if he lays the foundation and is not able to finish it, everyone who sees it will ridicule him, 30saying, 'This
fellow began to build and was not able to finish.'
