Broadband Indoor Antenna: by
Igor Grigorov, VA3ZNW
It was in winter 1994. In that time heavy winter winds
destroyed my outdoor antennas. I could not do repairs of the antennas
at cold winds and snowdrifts so I decided to try indoor antennas. I
tried several antennas at the times. The article describes one of them,
a very simple antenna that can work at all amateurs bands.
