1601354 L-Band Antenna

Radiation Pattern and Gain

The radiation pattern is adjusted omnidirectional. It has forward directivity to improve gain for ASAS, BCAS and TCAS. This adjustment in pattern and in gain improves reception and transmission characteristics while still meeting the following ARINC characteristics:

  • 709-1 (Distance Measuring Equipment)
  • 718 (Air Traffic Control Transponder)
  • 730 (ASAS)

A slightly eccentric radiation pattern allows the forward gain to approximate that of a vertically polarized quarter wave stub. The rearward gain is within 2.5 decibels below the forward gain.

Key Features

At least one L3Harris antenna is standard equipment on nearly every U.S. military aircraft flying today.

01

Extremely high side-load strength guards against breakage by ground handling gear

02

Completely sealed construction prevents moisture incursion failure

03

Lightning protection circuits prevent damage to antenna and safeguards electronic equipment
