Dual, Triple and Quad Feed Exposed Dipole Array
Dual, Triple, and Quad Feed Exposed Dipole Array The (2)871F-70, (3)871F-70, and (4)871F-70 are wide band multiple antennas designed for multicoupled systems. The antenna offers a choice of radiation patterns that are determined by the dipole-to-mast spacing. • These antennas have internal cabling and are not field adjustable. • Each antenna is offered in a 1/4, 3/8, or 1/2 wave pattern spacing versions. • Typical antenna to antenna isolation is 30dB, versions with 40 dB of isolation are also available. • Heavy duty versions are available. Please contact Comprod Inc. Technical support technician for consultation.
