HF Radio
Shortwave communications are essential for radio coverage on beyond-line-of-sight links over oceans and inhabited areas. Sigma Wireless has partnered with Rohde & Schwarz to bring you solutions that work in areas where VHF coverage is insufficient
The R&S®Series4100 adds long-range coverage to the CERTIUM® ecosystem for a high-quality integrated solution. In areas where VHF coverage is insufficient to sup[1]port a radio communications link over an air route's full length due to range limitations, the use of HF frequencies becomes necessary. These frequencies provide long-range radio link coverage for air-ground voice communications over major world air route areas (MWARAs) and regional and domestic air route areas (RDARAs) above oceans, deserts and other unpopulated territories. Since shortwave radio can sustain a radio channel beyond the line of sight (BLOS), it enables safe monitoring of air traffic through an uninterrupted radio link.
