When summer is back, I often like to go outside for HF portable operations. Personally, I do not like to carry too much equipment so I find the QRP approach quite appropriate to me. Operating QRP requires to select an efficient antenna. Sometimes, light wire antennas can be easily erected when natural supports are available… Read More

I am not going to explain the theory of this antenna since it is very well described in literature and on many web sites (see my links page) but, more practically, I would like to give here an overview of the successful designs I have tested and some useful tricks. However, just as a short… Read More

When deciding it was time to replace my homemade 4 elements 10 meters beam by a new directive antenna, I was expecting a type of antenna that would allow me to be active on multiple bands, ideally from 10 to 20 meters; and it had to be a homemade project. I had a large glance… Read More

After my 4 elements periodic logarithmic beam has been destroyed, I was again looking for a directive antenna with a simple design that could allow a coverage of all bands from 20 to 10 m. I found in a French magazine (MEGAHERTZ N°96, Feb 1991, F9HJ, p91-95) an original article about the W8JK: it was an… Read More
