Master Sgt. James Shearer, 28th Communications Squadron transmission system radio maintainer, uses a compass to determine the position for a new helical antenna prior to installation on Ellsworth Air Force Base, S.D., Feb. 13, 2012. Shearer installed the new antenna to secure data transfer between military installations across the U.S. (U.S. Air Force photo by Airman 1st Class Zachary Hada/Released)
Master Sgt. James Shearer, 28th Communications Squadron transmission system radio maintainer, assembles a AM-1 mount to correctly angle a new helical antenna being installed on Ellsworth Air Force Base, S.D., Feb. 13, 2012. The new antenna is capable of receiving satellite signals to allow continuous, secure data to be sent between military installations thousands of miles away.

Master Sgt. James Shearer, 28th Communications Squadron transmission system radio maintainer, assembles an AM-1 antenna mount on Ellsworth Air Force Base, S.D., Feb. 13, 2012. The antenna mount must be angled precisely so the new helical antenna can properly send and receive satellite signals. (U.S. Air Force photo by Airman 1st Class Zachary Hada/Released)
Master Sgt. James Shearer, 28th Communications Squadron transmission system radio maintainer, mounts and fastens a new helical antenna to a AM-1 mount used by the 28th Operations Support Squadron at Ellsworth Air Force Base, S.D., Feb. 13, 2012. The 28th OSS uses the antenna for joint range extension capabilities, to send and retrieve information via satellite. (U.S. Air Force photo by Airman 1st Class Zachary Hada/Released)
A new helical antenna is installed to replace a temporary antenna being used by the 28th Operation Support Squadron to provide optimal satellite communication capabilities at Ellsworth Air Force Base, S.D., Feb. 13, 2012. The helical antennas are built to withstand extreme weather conditions with dielectric rods along the mast, while the ground plane is backed with reinforcing ribs into which tubular axial rods are placed to increase the diameter of the ground plane.

Master Sgt. James Shearer, 28th Communications Squadron transmission system radio maintainer, adjusts the reflector rim on a new antenna for the 28th Operations Support Squadron on Ellsworth Air Force Base, S.D., Feb. 13, 2012. The antenna reflector focuses beam signals into a single point to help direct the radiating signal back to the point of origin. (U.S. Air Force photo by Airman 1st Class Zachary Hada/Released)
