Update on the W3EDP Antenna.......

A few years ago I wrote a blog entry on the W3EDP Antenna (HERE).  That article seems to be one of the more popular ones I have posted according to the stats for this blog.  The W3EDP is a good multi-band antenna that gets a bad rap from some sources, but it doesn’t deserve it at all.

Recently while surfing the net I can across a couple of articles written by Fred Benson, NC4FB, about some experiments he had conducted using the W3EDP antenna.  Knowing how popular this antenna is with the portable operators in Eastern Ontario, I had a good read of them.


There is some interesting information in those articles and I decided to experiment on my own.  I build my first W3EDP several years ago, and have used it mainly for Winter Field Day and Chillycon, places I want to get a working antenna up fast.

I chose to try the twin radial version, one radial of 33’ that is put in line for use on 80m and 40m, and a 17’ radial that is used for 20m to 6m.  Only one radial at a time is used.  Used with a 4:1 balun with these radials the antenna works like a charm.  I’ve also tried it with a 9:1 balun with success as well.  I’m going to use my analyser and record the difference between the two different baluns, and I will post that information here.

This antenna can be set up in any fashion that you like, inverted L, inverted V, sloper, or as a flat top, it works very well in any configuration.   It’s definitely worth while building and having in your antenna arsenal.

Another good article can be found HERE

More real experimentation is needed on this antenna.  Once the weather warms up I can get back at this..........hopefully next weekend! 


  1. Very interesting and as the weather warms and you get out and about to work on this antenna do post about it.
