Hello A

Your message below indicates that the RF isn't being radiated for the
benefit of your fellow hams, but is being absorbed by your household
devices!!

This is a good indication that your antenna is not working efficiently
and that Lou's original radiating antenna worked somewhat better than
the current commercial compromise equivalents!
