While level at altitude we experienced wind shear the aircraft dropped 2;300 ft.We tried to communicate the radio did not work. We got a back up radio. Received a call and made the launch recovery zone back hot.Recovered altitude and continued the mission. We also record a link hit at the same time.
Due to what we believe to be strong wind shear we were unable to maintain our altitude above 10; 000 feet. We began troubleshooting and attempted to communicate; but were unable to get through on our radios due to malfunction and had to grab a backup handheld. By this point we had descended roughly 2;500 feet when we established communication; at which point we made the mission hot again. We were then able to establish a climb and continue our mission.
UAS encountered wind shear and was unable to maintain altitude. Flight crew was able to regain control of the UAS and return to previous altitude.
