ROS with balcony antennaBy José Alberto Nieto Ros This antenna is used by EA5GTU/P during his holidays in La Manga (Spain). Besides of this antenna being low efficient on HF, he could contact with YV5MM (Venezuela) with ROS.
And this is an example of how you should not configure your Rig filter. In this case ROS frequencies below 1000Hz are lost in a Icom-7000. However the contact with YV5MM could be completed in the worst conditions.
