Thanks for the clarification on the above. I had based my previous post from here.

Finally, to avoid collateral damage to other vehicles, particularly on multi-lane highways, HPEMS is designed to optimize the antenna beam size, given operational frequency and the limitations of the antenna aperture size, which, together with system operational procedures (distance to the target vehicle and aspect angle) will assure the “illumination” of the target vehicle only. The tables below cite 1) HPEMS features, advantages, and benefits and 2) HPEMS comparison with other key competing technologies.
