Mark, could you please comment on the following from an alleged expert in the antenna field: Dick Jaffe >---------- >From: Dwight Lorenz[SMTP:lorassoc@sover.net] >Sent: Tuesday, July 21, 1998 11:56 AM >To: Dick Jaffe >Subject: RE: ITKG > >Dick, this is a message that young son received re ITKG. >Perhaps you could bounce it off the wizard in charge.
