[Antennas] Antenna-Related Patents

Mon Oct 13 14:48:55 EDT 2008

 Every once in a while I run across a patent where it's extremely obvious
that someone has patented public domain property by way of twisting language
around, such as the extensive ones granted to Parker Vision years ago. I
ran across a recent one of these yesterday evening:

 It's a simple choke balun made with a binocular core. These have been
around for so long that it's very likely that the prototype has
disintegrated back to dust. However, one look at the inventor's name made
it very clear what had taken place. Those of you who have been around this
hobby for any length of time will probably recognize the name right away.
The filing date is right around the time when this fellow was running around
on various lists claiming that baluns and transmission line transformers in
general did not exist.
 Some things never change.
