[Antennas] Insul wire vs bare ant wire length

[Merv Stump]

Insulated wire will be electrically long by from 1 to 3 percent.  In other
words cut your antenna 1 to 3 percent shorter than the formula would
indicate.  The only place I have found where this is significant enough to
make a difference is when dealing with something really big like 160 meter
half or full wave.
