Please explain in the area below why an STA is necessary:
This request for Special Temporary Authority (STA) is submitted pursuant to 47 CFR 5.61 to request authorization to perform a series of short flight tests for ground-based radar evaluation in support of a NASA contract. The STA is for frequency licensing of short-range panel radars made by EchoGuard operating in the frequency band 24450.000-24650.000 MHz with an Emission Designator of 45M0FXN. Operation within this frequency band requires FCC licensing.

Purpose of Operation
Please explain the purpose of operation:  The purpose of the operation is for Bell to gather air traffic data from Bell helicopters flying in the area as a part of the regular Bell Training Academy operations. Gathering of air traffic data using the EchoGuard radar system will allow for radar system performance evaluation.

Callsign: WQ9XMN
Class of Station: FX
Nature of Service: Experimental

Requested Period of Operation
Operation Start Date: 08/01/2020
Operation End Date: 10/30/2020

Is a directional antenna (other than radar) used?   No
Exhibit submitted:   No
(a) Width of beam in degrees at the half-power point:  
(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:   12.00
(b) Elevation of ground at antenna site above mean sea level in meters:   171.00
(c) Distance to nearest aircraft landing area in kilometers:   1.00
(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: Nearest aircraft landing area is the Bell Helicopter Floyd Carlson Field where the system is being setup. This area is covered by dense trees and with buildings spread throughout. Figure 3 in attachment shows surrounding area of blockage for frequency emission attenuation.
