In the EHF range, you get access to very wide bandwidths and highly directional links. That combination makes it easier to resist jamming and to support fast-moving platforms. The large available spectrum means you can spread or hop across many channels, complicating a jammer’s ability to disrupt the connection. At the same time, the use of highly directional, steerable beams confines the signal to a narrow path, reducing interference and allowing quick beam steering to follow a moving receiver or platform. Taken together, these traits give you strong anti-jam capability and good performance for high-mobility scenarios.
