Help,,, I don't have a clue what would be needed to shunt feed a tower for
160. Is one of the caps below what I would need .
I have never worked 160.. Might as well jump into the controversy.. I don't
have a tower up yet. Just planing ahead.

*********** Air Variable Capacitors ********
Cardwell enclosed 7 section variable capacitor assembly for/from some
receiver? -- The sections measure: 210, 210, 105, 105, 105, 100 & 75 pF.
The unit is about 12" long and 3" square with a right angle drive mounted
in the center and a 30 turn scale. This looks to be NOS (nothing ever
soldered to...) but, it is a mite tarnished on the outside from being
stored forever. There is also a (Mil?) number on the unit: SC3188A. $30

Johnson 154-1, 12-244pF, .05" air gap, about 3" x 3" x 3" overall.
Rear shaft has been cut flush with bushing and the rear mounting tab has
been shortened a mite. Otherwise, excellent condition, $25.
Johnson 154-34-3, 20-400pF, looks like .03" air gap, about 3" x 3" x 3"
overall not including 1/4" shaft which is about 2-1/2" long. Excellent
condition, $25.
Johnson 500E20 (modern equivalent 154-3), 500pF/2KV, looks like .05" air
gap, about 3" x 3" x 4.5" overall not including 1/4" shaft which is about
1-1/2" long. Good condition except the rear mounting tab has been
removed and it looks like a couple of the plates arced at one time and
were subsequently filed down a mite. $25.
Similar to the part above but, NOT a Johnson, another 500pF/2KV, looks
like .05" air gap, about 3" x 3" x 4.5" overall not including 1/4" shaft

has been removed. $25.
