[Antennas] Diminishing Returns - New Question

[Merv Stump]

Definitely do not strip the wire.  The insulation will have no affect on
performance; will be much easier to work with and will last longer.

However, if you are planning to cut the radials to resonance keep in mind
that insulated wire will be a little electrically long (probably somewhere
between 1 and 3 percent).  So you will have to cut them a little shorter
than you might have thought.
