HAVE YOU BEEN TOLD THE “SAME OLD STORY”?
Have you been told that you cannot get ILS service at your airport because the site is too difficult? Throw that old report away! We don’t believe it & neither should you. Click the Airport Improvement Magazine link button below, read the article regarding one of our installed End-Fire Antennas & you will see why!
End-Fire Antennas Can Offer Numerous Benefits Over Conventional Image Systems:
- Significant Cost Savings by Avoiding Expensive Ground Plane Conditioning.
- Provide ILS Service where Previously not Possible or Cost Effective due to Terrain.
- Proven Frangible Low-Profile Design Permitting “Next to Runway” Installation.
- Save the Wetlands or Avoid High Wetland Relocation Costs.
- Waterside Installations Since the Signal is not Degraded by Tidal Variations.
- Precision Glide Path Guidance is Achieved with Narrow Lateral Radiation
- Patterns that Reduce Multi-path Signals from Buildings or Mountainous Terrain.
