Welcome to my web site!

 

After ignoring or perhaps avoiding this new technology for a number of years I can see that it has matured and become, for many, a part of normal life. So at the urging of my family and friends I have decided to use the "Web" to communicate my recent developmental work on the "Pfeiffer Quad antenna system" as well as some other designs.

I have in the last several years spent a lot of time working with Quad antenna systems. The antenna is the critical, if not the most important piece of equipment comprising an efficient radio  station setup.

I started with the cubical quad. In particular, I set out to correct its one great quality ...its inability to withstand violent wind and ice storms, a failure that most quad owners the world over have experienced... the negative quality of self destruction..

Reducing a normal size antenna, independent of type and configuration, is a simple matter, but to do this and still maintain the antenna’s original efficiency, comes down to choosing the proper course of action. Inserting loading coils, and/or capacitors, introduces losses which are unacceptable. I chose linear loading, and the system I have applied to the elements of my quads has accomplished a great size reduction without deterioration of the full size antenna performance.

 The perimeter of my linear loaded quad resembles that of a Maltese cross, and thus came the birth of the “Pfeiffer Maltese Quad”.

On this site you can see pictures of the antennas that I have built. Read and download the article that I have published on my designs, and read some of the feedback that I have received from others.
