WATTS ANTENNA COMPANY ...the tough site solution

The WATTS MODEL 201 HIGHLY DIRECTIVE LOCALIZER SYSTEM provides final approach azimuth guidance information to a landing aircraft, enabling the pilot, or autopilot, to maintain the proper course during the approach and landing.  The Model 201 is engineered to provide Category III ILS signal quality for the most complex airport environments in the world and represents R&D in ILS antenna system design well ahead of today’s standards.

• Substantially Reduces ILS Critical and Sensitive Areas

• Provides Maximum Runway Capacity, Allowing Increased Airport Development and New Construction.

• Modular Course Antenna – Adjustable Antenna Aperture

• Frangible Design

• Minimize Coaxial Cable and Low Tune-up Time – Adjustment by Trimming One Coaxial Cable

• Three Configurations:

1. Model 201 Wide-Aperture Slotted Cable Course Antenna: The narrow course beam produces Category III signal-in-space course structure quality and adequate signal levels to meet all FAA usable distance requirements.
    

2. The 8-Element LPD Reduced Clearance-Sector Antenna Array: Provides limited azimuthal coverage with course roughness comparable to a 14-element array since energy is suppressed outside +/- 15 degrees in azimuth and meets usable distance.
    

3. The Model 201-8 Two Frequency Localizer System:  Combination of the Model 201 Wide-Aperture Slotted Cable Course Antenna Array with the 8-Element LPD Reduced Clearance-Sector Antenna Array meets all FAA Flight Inspection requirements.
