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.
