The EMR450DP4 dipole array is a rugged broadband antenna for use in the 360-520MHz band. The dipoles are all welded and polished Stainless Steel construction suited to all harsh environments. The array can be mounted in three configurations to allow for different shaped radiation patterns in the H plane, including 1/4, 1/2 and full wavelength spacing from the vertical mounting pole. The antenna configuration includes all necessary mounting brackets and phasing harness to stack the antennas for increased gain.
