Directional Antenna

Is a directional antenna (other than radar) used? See antenna legend above.

If yes, provide the following information:
i.    Width of beam in degrees at the half power point:    N/A
ii.   Orientation in horizontal plane (degrees):           N/A
iii. Orientation in vertical plane (degrees):              N/A

Antenna Height

Will the antenna extend more than six meters above the ground, or if mounted on an existing
building, will it extend more than six meters above the building, or will the proposed antenna be
mounted on an existing structure other than a building? Yes

If yes, provide the following information:
I     Overall height above ground to tip of antenna (in meters):
        Spiracone, Andrews 3001-3ML: 39.6 meters above ground
        Spiracone, Andrews 3002-3ML: 10.2 meters above rooftop of FRC
        Log Periodic Antenna, USA Towers, RLP-2: 40 meters (estimated) above ground
ii    Elevation of ground at antenna site above mean sea level is: 196 meters
iii   Distance to nearest aircraft landing area (in kilometers):       10.10 km
iv    List any natural formations of existing man-made structures (hills, trees, water tanks,
towers, etc.) which, in the opinion of the applicant, would tend to shield the antenna from
aircraft and thereby minimize the aeronautical hazard of the antenna. None
