d. Authorization of a developmental allocation does not assure
subsequent authorization of an operational allocation or assignment.
Revisions of frequency allocation tables, changes in equipment
characteristics,
military
standards,
density
of
the
intended
operational environment, and international agreements, among other
things, all may adversely affect authorization of an operational
allocation when new equipment enters the procurement phase.
On the
other hand, developmental allocations are seldom granted when it can
be ascertained that an operational allocation cannot be supported.
In those few cases, the developmental allocation is normally
authorized for concept development purposes only.
e. Among the requirements for granting an operational frequency
allocation are:
(1) Completion and submission of a DD Form 1494.
(2) Conformance of the technical
characteristics
to
all
the
constraints of the applicable standards.
(3) Assurance of tuning flexibility and frequency
support
within the appropriate allocated band of frequencies.
(4) Design of the equipment to comply with
the
specific
allocation guidance provided on a case-by-case basis.
(5) Design of the equipment to be in conformance with Military
Communications-Electronics Board guidelines.
f. Measured spectrum signature data, theoretically synthesized
data, or both, may be required prior to completion of the operational
allocation.
30. Frequency Assignments.
a. As
previously
stated,
frequency
assignments
constitute
authority to use a portion of the spectrum at specifically identified
localities and within specific technical characteristics. Within the
United States and Possessions, Department of the Army frequency
assignments
fall
into
three
broad
categories:
first,
those
assignments used for command and administration (nontactical) on a
permanent basis (operations for periods longer than six months);
second, those assignments used for tactical and training purposes;
and third, those experimental assignments in support of more than six
months are processed from the applicant, through the appropriate Area
Frequency
Coordinator,
to
Assistant
Chief
of
Staff
for
Communications-Electronics.
