This new video is to announce the English translation of the "cizirf-Special" antenna description. This is a broadband receiving antenna optimized for short an medium distances. The soundtrack has been recorded on 80m with I1 stations, located about 150 kms from home, just using a simple version only 1m AGL where the phase-shifts were obtained by means of switched coaxial lengths. On the video you can see the 80m patterns, simulated with NEC2 (4Nec2 by Arie Voors) for 0, 45, 90, 112.5, 135, 157.5, 180, 202.5, 225, 247.5, 270 and 315 degrees (the rotating one being for 125 degrees). This antenna was initialy designed with our "national contest" in mind, but I am sure you will find many other applications.
You may not believe the 30dB claim... then have a look at this video !
