The Telewave ANT400D6-9 antenna consists of four-element dipole array with a precision phasing harness for optimum performance. The antenna horizontal pattern is field adjustable, for any current or future coverage requirements. The wide bandwidth and high efficiency of these antennas make them ideal for many applications, including military communications, TETRA trunking, and amateur radio. Each dipole element is constructed with 6061-T6 aluminum and welded at the base for maximum strength. Each antenna is also completely sealed with our high tech Txylan(TM) coating, which resists water and ice buildup, and provides exceptional protection from corrosive gases, ultraviolet (UV) radiation, salt spray, acid rain, and windblown abrasives. The phasing harness is fully sealed by Telewave’s Millennium Seal(TM) technology. All components are at DC ground potential for lightning protection. Each dipole element includes a heavy-duty custom clamp set for mounting to a 1.5 in – 2.5 in diameter galvanized steel support pipe or tower leg. Up to 15 deg. of electrical uptilt or downtilt may be specified for D3 or D6-9 models. The desired tilt angle must be included on the order, and consultation with our antenna engineering staff is requested.
