Terry,

You don't need a capacitor rated that high, as long as you don't make it
much longer than 1/4 wave on 160. Ohm's Law is your friend, just use one of
the formulas to calculate E from R and P.  :-)

... All this talk about inv-L's has got me wondering about adding a second
one longer than my '1/4WL' one. But being so cold and the possibility of
messing of the operation of what I have now has kept me from trying a
longer inv-L. That and not being sure exactly how much and how high of
voltage a variable capacitor I would need. I do have some 500pF 10KV
doorknob cap I can parallel a variable cap with. And now hearing I might
need longer radials. An acres and a half only allows only about one 160
meter antenna at a time along with my other ones.
