  Welcome

  I created this web site to deal with all the little sheets of notebook paper, and sticky notes in books.

I worked in radio since 1968, and in engineering since 1977, and in TV and structural engineering starting in 1985.

  The numbers I give in these articles are as close to being real as possible. But in all application you need to "adjust" for optimum performance. In all my years, I've never taken an antenna out of a box, or built one from a book, that has not had to be adjusted in the field. There are always factors such as near field contaminance, grounding issue, impedance problem. Get used to having to tweak.

  The categories on the left and right contain links to the articles. Many I have made personally, and some I have made several times for friends and radio club projects. I'm always happy to give sage advice to antenna builders, but I can't make antennas for you, or provide parts.
