[Elecraft] Running high power

[Steve Hall]

Certainly as you increase power you are more likely to cause undesirable
effects in the home.  Now I am going to make a generalization that I have
found true.  The antenna type makes a significant difference in
interference.  Unbalanced antennas introduce more RF into the home as
opposed to balanced antennas.  An end-fed or off-center fed causes far more
problems than a dipole or inverted Vee.   I have proven this to myself over
and over.
