Operating both NVIS and long distance sky wave.
As well as the compact mobile HF loop, two versions of fixed station loop antennas are also available, which operate on both NVIS and long distance sky-wave propagation modes across 3-30MHz.
The two versions are a wire element loop with 3m sides, and a solid element loop with 2.5m sides, each offering similar high efficiency. These are ideal for use where space is limited, and rival the performance of much larger wideband HF wire antennas.
Like the mobile loop, the fixed station loop is capable of automatically tuning across its frequency range in less than a 50th of a second. It is compatible with virtually any HF transceiver including frequency hopping types without the need for a separate control.
