Explanation

Please explain in the area below why an STA is necessary:
Requesting authorization to transmit HF waveforms from a lofted platform to calibrate the ROTHR radar

Purpose of Operation

Please explain the purpose of operation:

To transmit HF waveforms from a lofted platform to calibrate the ROTHR radar. This hardware development is being funded through an IRAD program at JHU/APL to develop test hardware for use with the ROTHR radar. It will only be used in the US. This specific STA request is for approval to transmit waveforms from a lofted platform as allowed/authorized by the FAA. The frequencies listed in this STA request have been negotiated with ROTHR representatives. The hardware for this test has been checked for proper operation at JHU/APL in Laurel MD under STA authorization 0781-EX-ST-2013, granted 8/27/2013. The Program Manager of this effort at JHU/APL is Hans Widmer (240-228-2977, [email protected]). These tests may be repeated near Camp Lejeune, NC later in 2013 or early 2014.

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? No
(a) Overall height above ground to tip of antenna in meters:
(b) Elevation of ground at antenna site above mean sea level in meters:
(c) Distance to nearest aircraft landing area in kilometers:
(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 will be lofted on a weather balloon that is expected to reach 70 kft. Authorization to launch from Fayetteville is being coordinated with the FAA. Over the ascent and descent, the balloon is expected to stay within a radius of 200 km of Fayetteville, NC
