  Welcome

  I created this web site to deal with all the little sheets of paper, sticky notes, old books, and white papers which have cluttered my desks for decades.

  I was a radio hobbyist long before I started working in radio. In April 1968, after receiving my F.C.C. license, I had my first radio job. I started working in professional recording and engineering in 1977, and TV & HF broadcasting in 1985. I'm now retired from engineering practice, enjoying the radio hobbies.

  The numbers I give in these articles are as close to being real as possible. But in all applications you must "adjust" for optimum performance. In all my years, I have 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 contamination, grounding, use of materials, or understanding how antennas work. Get used to having to tweak... it's part of the process.

  The categories on the left and right contain links to the articles. Many I have made myself, and some I have assisted friends build. I'm always happy to give sage advice, but I can not make an antenna for you, or provide parts. Please do not expect any urgency in replying to emails, or engaging in long, detailed email exchanges.

  When it comes to on-line forums, Facebook, and other social media ... take what people say with a grain of salt. Because they say it works for them, does not mean it will work for you. Some people, (regardless of license or stated credentials), toss out advice or comments which they know nothing about. And there is a portion of people who comment for the sake of commenting without knowing what they are talking about. Antennas, especially around power lines, are lethal. Antennas can, and have, attract lightning. So before taking the word of someone on-line, who you don't know, do your own research on the subject.
