KT-34, that is.

Connect a dc ohmmeter between the 10 meter and 15
meter trap capacitor outer tubes on each element half.
After correcting for ohmmeter lead resistance, the
total resistance should be less than 0.5 ohm. This
one measurement tests all of the critical connections
on each element half.

Then connect the ohmmeter across the two halves of
the rear driven element. Once again, it should read
less than 0.5 ohm. This one measurement tests all
the connections through the phasing straps, matching
assembly and balun.

Make sure that the wall thickness of the outer capacitor
tubes is .049", not .058". Incorrect tubing was supplied with
some antennas.
