The Department of Defense, specifically the Marine Corps, is seeking innovative solutions for a compact, lightweight directional antenna that operates within the High Frequency (HF) and Very High Frequency (VHF) ranges, specifically from 1.5 MHz to 90 MHz. The objective is to develop an antenna that maximizes gain in a desired direction while minimizing gain in the opposing direction, with a significant drop in power radiated in the undesired direction. This technology is crucial for military communications, particularly in tactical scenarios where minimizing detectability is essential. Interested parties should note that the solicitation is currently in pre-release, with the open date set for January 8, 2025, and the application due date on February 5, 2025.
