[TowerTalk] Capacitors To Tune 160 Vertical

[Jim Brown K9YC]

Crew,

I'm thinking of following N6LF's advice on a rebuild of my 160 
vertical by tuning it low and adding series capacitance to tune out 
the resistance to match it to 50 ohms. Legal power will put about 
220VAC across 2.2 nF, at a little less than 6A. I think my greatest 
concern is dissipation from the ESR of the cap. Once I get this 
working, I'll probably do something similar for 80M.

My question is about what capacitors will work. I'm looking for 
about 2.2 nF (2,200 pF), and I'll run legal power with the fairly 
high duty cycle of a contest. I've got some 3kV and 6kV caps in the 
100-500 pF range, and some 400VDC caps in the 10-100 nF range. I 
could series the LV caps or parallel the HV caps. Does anyone have 
experience or an educated guess?   

73,
