Fixed Base NVIS Loop Antenna
Operating both NVIS and Long-Distance Skywave.
In addition to the Hilmoast, LLC Compact Mobile HF loop, two versions of the Hilomast Fixed-Station Loop Antennas are also available.
These Hilomast Fixed-Station Loop Antennas operate on both Near Vertical Incidence Skywave (NVIS) and Long-Distance Skywave propagation modes across 3-30MHz.
The NVIS and Long-Distance versions are a wire-element loop with 3m sides, and a solid-element loop with 2.5m sides, each offering similar high-efficiency.
These NVIS and Long-Distance Skywave antennas are ideal for use where space is limited.
The NVIS and Long-Diatance Skywave antennas rival the performance of much larger Wideband HF wire antennas.
