Is a directional antenna (other than radar) used?
Yes
Exhibit submitted:
Yes
(a) Width of beam in degrees at the half-power point:
0.50
(b) Orientation in horizontal plane:
(c) Orientation in vertical plane:
Will the antenna extend more than
6 meters above the ground, or if mounted on an existing building,
will it extend more than 6 meters above the building, or will
the proposed antenna be mounted on an existing structure other
than a building?
Yes
(a) Overall height above ground to tip of antenna in meters:
30.00
(b) Elevation of ground at antenna site above mean sea level in meters:
132.00
(c) Distance to nearest aircraft landing area in kilometers:
18.00
(d) 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:
The antenna to be used is the 60 diameter parabolic dish/system. It has been in use since 1963 with several upgrades, operating now in S/X-bands in support of various NASA space missions. Impact to aviation is mitigated in several ways including shutting off transmissions when antenna is pointing below 10 deg elevation (minimize impact on airport systems), no transmissions in aviation bands, and a 0.5 deg 3dB beamwidth (see Antenna Drawing" exhibit).
