FreeFlight Unveils Radar Altimeters that Mitigate 5G Effects
New radar altimeters from FreeFlight Systems are designed to withstand interference from 5G products.

FreeFlight Systems has unveiled a new series of radar altimeters with “redesigned RF circuitry built to withstand 5G interference.” The new Terrain Series RA 5500, RA 6500, and RA 7500 are optimized for heavy rotorcraft, turboprops, business jets, and military aircraft and will be available in October.

Radar altimeters are facing interference problems from 5G terrestrial broadband datalink systems, such as new 5G products. According to FreeFlight, “Decades ago, when the original specification was created for the radar altimetry, the radio frequency (RF) environment was protected.” That is no longer the case with new products such as 5G.
