The HW and HWR Series antennas now include 2.45 GHz models. The 1/2-wave, center-fed dipole antennas come in rugged and physically attractive packages. The HW has a fixed base while the HWR features an articulating base that allows tilting of the antenna up to 90° and 360° rotation. Both models employ an internal counterpoise that eliminates external ground plane dependence. ANTENNA FACTOR, Merlin, OR. (800) 489-1634.
