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.
