Model SD-127 118- 37MHz 3 dBd. Gain Download Datasheet Download Manual Post Enquiry

High Gain ATC Antenna

Design Features: The SD-127 Aviation Band Antenna is manufactured using high-grade anodized aluminum. Powder coating of the complete aviation band antenna provides extra protection against corrosion in saline weather present in coastal areas. The SD-127 stacked dipole array operates at DC ground from protection against lightening, does not require any field tuning or adjustment and is highly suitable for ground-to-air communication with ATC sites without having the requirement of multiple antennas. The SD-127 is heavy duty stacked dipole array features, wide bandwidth, high gain, high power handling capacity, low VSWR, low noise performance and null filling coverage with omni directional characteristics.

Constructions:The SD-127 Stacked Dipole Array consists of TWO folded dipoles stacked vertically, fed in phase. This Stacked Dipole Antenna operates at D.C. ground for protection against lightning. Termination of phasing harness cable sealed by heat shrinking tube making stacked dipole antenna waterproofing. The 3 Meters long central mast for mounting the dipoles is shipped in two sections of 1.8 Meters each for easy of shipping. The stacked dipole antenna is suitable for mounting on the top of tower and is supplied with two mounting brackets.

Radiation Pattern: When the TWO dipoles are arranged 180 degrees apart around the central mast, 3dBd. (5.15dBi) omni directional radiation pattern results. Aligning the TWO dipoles collinearly (facing in one direction) a 6dBd. (8.15dBi) offset radiation pattern can be obtained. The radiation pattern can be changed in the field by use of common hand tools.
