Thanks for the nice plug, Billy - In a computer disaster here, I lost my 
electronic copy of that article.  If anyone has it on CD and could send it 
to me I'd sure appreciate it, and will post it on my web site.  Don't worry 
about copyright - by NCJ's rules I retained that post-publication.

In the same mode, if anyone has an electronic copy of my September-October 
2001 followup on my "Scoring" Your Antenna System article, I'd appreciate 
that too.  It corrected some blunders in the original article, and is 
listed in the NCJ index as Shorts: "Scoring"Your Antenna System N4ZR 01 
Sep/Oct 37

Thanks in advance!

73, Pete N4ZR
