[Elecraft] Dipoles and Heat

[Ron D'Eau Claire]

Assuming the heat question was from a safety standpoint, I'd be more
concerned with corona discharge than heat. 

Many attic antennas have very limited attention paid to insulating the
high-impedance points, assuming the dry wood rafters are adequate. There are
been reports of fires caused by just such assumptions where the high
impedance end of the wire was near dust and other combustible materials.
