USACESO will provide MACOMs a copy of the DD Form 1494 for their use in developing spectrum engineering tools and conducting EMC analyses. When necessary, USACESO will, after coordination with appropriate command spec- trum coordinators, furnish guidance to the developing activity re- garding impact of equipment use on established Army services. (3) Receivers and antennas developed independently. Developers of receivers and antennas will complete a DD Form 1494 for each receiver and antenna developed independently of transmitters or receivers. (4) Non-tactical, commercial, land mobile radios (LMRs) pro- cured without a DD Form 1494/ military nomenclature.
To maintain accurate information and databases of Army telecommunications equipment using Army spectrum resources, MACOMS will submit a DD Form 1494 for those equipment already procured without a DD Form 1494 and in use at the MACOM. For anticipated procurement of new non-tactical, commercial, intrabase radios, commanders of MACOMs (posts, camps, and stations) must submit a DD Form 1494 for approval prior to procurement of the equipment to the USACESO (SFIS-FAC-P). Also, prior to contractual commitments, f r e q u e n c y a s s i g n m e n t s m u s t b e a v a i l a b l e a s d e t e r m i n e d b y t h e USACESO or AFC. environment.
It may take 6 to 12 months to coordinate with host countries for frequency spectrum support. Therefore, originators will submit the DD Form 1494 during the LCSMM, as follows: (1) Stage One—Planning (Conceptual); Phase I, LCSMM: submit per type of system below: (a) Space Systems (including earth stations and terminals): sub- mit 4 to 6 years, but not less than 2 years, before planned satellite launch. (b) Terrestrial Systems: submit 3 years, but not less than 1 year, before planned procuring for experimentation. (2) Stage Two—Experimental; Phase I, LCSMM: submit not less than 6 months before procuring for experimentation. (3) Stage Three—Developmental:
submit in order to be approved before Milestone I Review, or appropriate IPR, per type of system below: (a) Space Systems: submit 2 years, but not less than 1 year, before a development contract award. (b) Terrestrial Systems: submit not less than 6 months before a development contract award. (4) Stage Four—Operational: submit in order to be approved before Milestone II Review or appropriate IPR. Submit at least 6 months before acquisition actions for all equipment that use satel- lites or spacecraft or have significant impact on the electromagnetic f r e q u e n c y s p e c t r u m . F o r a l l o t h e r e q u i p m e n t , s u b m i t a t l e s t 4 months before acquisition actions.
Data on DD Form 1494 should be validated through measured data when possible. 4–5. EMC and DD Form 1494 Reviews Required by the NTIA a. Reviews of certain new Federal Government telecommunica- tions systems by the SPS are required prior to committing funds, entering into contracts, and assigning frequencies. These reviews apply to the following types of telecommunications systems: (1) New space telecommunications systems or subsystems, as well as major modifications to existing systems, that involve the use of satellites or spacecraft.
(2) New terrestrial telecommunications systems or subsystems, as well as major modifications to existing systems, that have signifi- cant impact on the use of the electromagnetic spectrum. (3) New, major, digitized voice systems, including modifications to existing systems or subsystems, that involve the 30-88, 138-174, and 406-420 MHZ bands. (4) All systems in the 14.4-15.35 GHZ band. (5) Systems or facilities that the NTIA, IRAC, or other Federal Government agencies refer to the SPS. Referral may result from factors such as system costs, importance, or from estimates of unu- sual or potential impact on other spectrum uses. b. USACESO will submit the DD Form 1494 to the SPS for review.
After reviewing the proposed system, the SPS will submit recommendations, with supporting documents on spectrum availabil- ity, through the IRAC to the NTIA. c. The NTIA review will be returned to the Army originator through USACESO. In addition to the NTIA review, USACESO will prepare a LOT for approval by the Army Spectrum Manager which may include additional guidance, restrictions, and specific actions. The originator must comply with the instructions in the r e v i e w a n d t h e L O T . T h e o r i g i n a t o r w i l l s u b m i t a l e t t e r t o USACESO stating how the recommendations and guidance of the review and LOT will be implemented.
USACESO will keep the A r m y S p e c t r u m M a n a g e r , M A C O M s p e c t r u m c o o r d i n a t o r s , a n d other interested Army commands and agencies informed of the originator’s progress in complying with the review and LOT imple- mentation guidance. d. If the NTIA review and the Army Spectrum Manager LOT both indicate disapproval, the originator will resubmit the DD Form 1494 when corrective action has been completed. 4–4. Processing DD Form 1494 a.
Army personnel involved in the conceptualizing of research, d e v e l o p m e n t , p r o d u c t i o n , p r o c u r e m e n t , m o d i f i c a t i o n / p r o d u c t i m - provement, and lease or use of spectrum-dependent materiel will initiate the Frequency Allocation-to-Equipment Process by complet- ing and submitting DD Form 1494 with supporting documents (e.g., spectrum supportability/EMC assessments) to addressees indicated in Paragraph 4-3a. b. USACESO will review the DD Form 1494 for completeness, accuracy, and initial determination of spectrum supportability. The DD Form 1494 will then be distributed to other organizations in parallel.
This distribution may include the USMCEB, AFCs, holders of DD Form 1494s, the JSC (AR), and the NTIA/SPS if appropriate. c. The military departments, unified commands CINCs as appro- priate, and the JSC will review the form and provide EMC com- ments on the DD Form 1494 to the J-12 permanent Working Group. d. The J-12 permanent Working Group will review the DD Form 1494 and the EMC comments to determine if the equipment or system can receive spectrum support in the geographic areas speci- fied on the form. If the equipment or system is to be used outside of the US&P, unified command (CINCs) and host nation concurrence is required prior to approval. e .

The guidance will also include recommendations of specific actions for approval or implementation. The memorandum will be returned to the originator through the USACESO. In addition to the memo- randum, USACESO will prepare a LOT for approval by the Army Spectrum Manager that contains additional guidance, restrictions, and specific actions. The originator must comply with the instruc- tions in both the memorandum and the LOT. f.
If there is a conflict between the USMCEB and the Army Spectrum Manager, then the papers (USMCEB memorandum, the DD Form 1494, and the JSC EMC comments) will be forwarded to the USMCEB Joint Frequency Panel (JFP) for resolution. g. If the memorandum and the Army Spectrum Manager’s LOT indicate approval with implementing guidance, the memorandum is then signed by the J-12 Working Group chairman. h. The USACESO and USMCEB reviews normally take 90 to 120 days, depending on the type of equipment and its operational 4–6. Waivers and Exceptions a. Allocation approval waiver.
If exceptional circumstances will not allow enough time (normally 90-120 days) to process a DD Form 1494, a “Release of Funds Waiver” may be requested. Such a 14 AR 5–12 • 1 October 1997
