Regarding directional antennas, I'm referring more to a log periodic antenna that roughly directs RF in a 45-60 degree arc [1]. Placed around the perimeter of a base, there's enough directivity that an incoming drone is being hit with 100-1,000x more RF energy than things inside the perimeter. It's not a "drone gun", it's still jamming an area. It's just wedge shaped area facing away from you. And yeah, the most effective way of avoiding EF friendly fire is spread spectrum communication where the jammer is synchronized to avoid the frequencies being used for communications. But that can be tricky to set up, since you have potentially many different radio systems with their own spread spectrum scheme. 1. https://www.tutorialspoint.com/antenna_theory/images/uni_directional_log_periodic.jpg https://www.tutorialspoint.com/antenna_theory/images/uni_dir...
