MIL-PRF-49204B(CR)
3.8.7 Drop. The antenna system, disassembled and stowed in its bag,
shall be capable of being repeatedly dropped a distance of 30 inches onto any
surface or edge without harmful damage to any component or to the bag. (See
4.14.5)
3.8.8 Wind/ice Load. The antenna system, when erected for field
operation according to the instructions, shall be capable of withstanding 90
mile per hour winds without ice load and 60 mile per hour winds with 1/2 inch
of radial ice and remain erected, without harmful damage to the feedcone
structure, to the balun, or to the mast including the guy system. (Note that
the test specified herein is for 90 mph winds only since this is easier to
implement and performs essentially the same purpose as a combined wind/ice
load test). (See 4.14.6)
3.8.9 Immersion. The antenna system, stowed in its bag (less Technical
Manual and Cable Assembly CG-1889 C/U), shall be capable of being immersed to
a covering of 3 feet of fresh water for a period of 2 hours. The immersion
shall not result in any form of physical deterioration, loss of fit, or
reduction in electrical performance below specified limits. (See 4.14.7)
3.9 Running Spares. A set of running spares shall be furnished as
specified in the contract or purchase order.
3.10
Systems Safety Engineering.
3.10.1 Personnel Hazards. Personnel hazards shall be kept to a
minimum. Tasks and efforts such as selection of parts, the complete
manufacturing and assembly process, and any product baseline configuration
changes that may be implemented during the course of the contract.
Verification that compliance with this requirement has been achieved shall be
verified through visual inspection.
3.10.2
Corona.
The feedcone structure shall be free of sharp edges and
points.
3.10.3 Radioactive Materials. Radioactive materials shall not be used
(e.g. luminous dials/markings, electron tubes, surge arrestors and lenses).
3.10.4 Edge Rounding Exposed. Exposed edges shall be rounded to a
minimum of 0.04 inch (1 mm), and exposed corners to a minimum of 0.5 inch (13
mm).
3.11 Workmanship. Standards of workmanship shall be such that
components will meet all requirements of this specification and any referenced
drawings when inspected in accordance with Section 4. The equipment shall be
fabricated in such a manner as to be uniform in quality and shall be free from
defects that will affect their life, serviceability, interchangeability, or
appearance. (See 4.12.1)
