CONSTRUCTION The AME Field will form an isosceles right triangle with
503-ft. legs. Surface material in the AME Field area will be homogeneous
to a depth of at least six feet and the surface will be level to within + 2 inches.
Thirteen concrete antenna pedestals will be constructed in recessedconcrete
pipe wells. TC furnished antennas will be positioned on the pedestals to within
first order survey accuracies both horizontally and vertically. Reflecting surfaces may not be located nearer than 200-ft. to the field edge; beyond this, they
may not extend more than 2 degrees above the horizon in the north-south and 4
degrees in the east-west directions.
A TC furnished AME Recording Van and a Shop Van will be located approximately 200-ft. north of the field. A multi-plate steel arch, covered with coral,
will be erected over the AME Recording Van to provide protection. The arch
will be approximately 45-ft. in length and will be open at both ends. The Shop
Van will be unprotected.
Two 72 kva, 4160-120/208 volt,
60 cycle,
3 phase transformers will provide
utility power and instrument power to the two (2) trailers.
