Quad Plot Results
This is a 20 meters audio plot with a signal generator at the end of the garden. Due to small distance and negative plot angle relative to the main elevation beam of 20 degrease is not surprisingly poor.
15 meters Audio Plot
This is the result of and audio plot on 15 meters. The signal source was a very strong RADAR pulsing systems monitored in AM receive mode. The antenna height is 35 meters
10 meters Audio Plot
This is a 10 meter plot with the same signal source. Both plots are not ideal and do not represent, I believe the true performance of the antenna due to unreliable measuring techniques. These will be replaced shortly when I have time to do a correctly calibrated test, at true RF level, and not at audio.
