Question 9: Statement of Environmental Impact

ELTA North America (N.A.) will occupy a section of the building located at 11840 West Market
Place. Fulton, MD. The building is a new, single-story structure, with multiple bays, and is constructed of
concrete block with a web girder and steel pan roof. The surrounding area is a mixed-use development of retail,
office, educational, and residential buildings. The adjacent property consists of similar single-story buildings to
the north and south of the site, a public school campus to the west, and an open field to the east. Further north is
a residential neighborhood and the Johns Hopkins University (JHU) Applied Physics Laboratory (APL)
campus. Further east is a small urban development with multistory buildings. The antenna will be mounted on
top of a four-to-six foot mast which will be located on the roof. The radar equipment will be remotely
controlled from inside the building.

ELTA N.A. intends to demonstrate the EL/M-2180 radar to the U.S. Army at Ft. Benning, GA. The
demonstration will take place in the area surrounding the McKenna Leyte Heliport located on base. This site
consists of remote and relatively flat open fields and forested areas. The radar will be located on a tripod or
short mast with a height of approximately 1.2 m, and will be remotely operated. In addition demonstrate the
EL/M-2180 radar to the Costumes and Border Protection (CBP) DHS at Sells (Elephant Head,Horse
Peak) ,AZ in PIMA county. This site is isolated open desert and hilly area ,The radar will be located on a
tripod with a height of approximately 1.2 m, and will be remotely operated

It is the policy of ELTA N.A. that company personnel, customers, or members of the public are not subjected to
RF power density levels that exceed the Maximum Permissible Exposure (MPE) limits as given in Part 1.1310
of the FCC Rules. Experimental testing will only be conducted with appropriate controls in place, and no
personnel will be on the roof during transmissions that will exceed the MPE levels. ELTA will have an RF
Safety Plan which describes the procedures and controls necessary to comply with MPE levels during
operations and maintenance.

ELTA N.A. conducted a worst-case analysis of power density levels in the area surrounding the transmitting
antenna based on the FCC's OET Bulletin Number 651. The applicable radar parameters and results are shown
in Tables 1 and 2, respectively. For the Fulton, MD site, with a building height of approximately 19 feet and a
width of 86 feet, the line-of-sight distance to a six-foot person standing on the ground is 184 feet. This assumes
that the antenna center is 4 feet above the roof. Consequently even under worst-case conditions personnel on
the ground will be beyond the distance where the power density exceeds the MPE limit. For the Ft Benning
location, considered as a controlled environment, participants of the demonstration will be kept a minimum of
6m from the radar antenna.
