FCC Declaration of Conformity
1. Sea Tel, Inc. designs, develops, manufactures and services marine stabilized antenna systems for
satellite communication at sea. These products are in turn used by our customers as part of their Ku-
band Earth Station on Vessels (ESV) networks.
2. FCC regulation 47 C.F.R. § 25.222 defines the provisions for blanket licensing of ESV antennas
operating in the Ku Band. This declaration covers the requirements for meeting § 25.222 (a)(1) by
the demonstrations outlined in paragraphs (b)(1)(i) and (b)(1)(iii). The requirements for meeting §
25.222 (a)(3)-(a)(7) are left to the applicant. The paragraph numbers in this declaration refer to the
2009 version of FCC 47 C.F.R. § 25.222.
3. Sea Tel hereby declares that the antennas listed below will meet the off-axis EIRP spectral density
requirements of § 25.222 (a)(1)(i) with an N value of 1, when the following Input Power spectral
density limitations are met:
*0.6 Meter Ku Band, Models 2406 and USAT-24 are limited to -21.6 dBW/4kHz
*0.75 Meter Ku Band, Models 3011 and USAT-30 are limited to -21.6 dBW/4kHz
0.9 Meter Ku Band, Model 3612 is limited to -20.3 dBW/4kHz
1.0 Meter Ku Band, Models 4003/4006/4009/4010 are limited to -16.3 dBW/4kHz
1.0 Meter Ku Band Model 4012 is limited to -16.6 dBW/4kHz
1.2 Meter Ku Band, Models 4996/5009/5010/5012 are limited to -14.0 dBW/4kHz
1.5 Meter Ku Band, Models 6006/6009/6012 are limited to -14.0 dBW/4kHz
2.4 Meter Ku Band, Models 9797 and 9711QOR are limited to -14.0 dBW/4kHz
4. Sea Tel hereby declares that the antennas referenced in paragraph 3 above, will maintain a
stabilization pointing accuracy of better than 0.2 degrees under specified ship motion conditions,
thus meeting the requirements of § 25.222 (a)(1)(ii)(A). Those antennas marked with * will
maintain a stabilization pointing accuracy of better than 0.3 degrees. The Input Power spectral
density limits for these antenna have been adjusted to meet the requirements of§ 25.222 (a)(1)(ii)(B).
5. Sea Tel hereby declares that the antennas referenced in paragraph 3 above, will automatically cease
transmission within 100 milliseconds if the pointing error should exceed 0.5 degrees and will not
resume transmission until the error drops below 0.2 degrees, thus meeting the requirements of §
25.222 (a)(1)(iii).
6. Sea Tel maintains all relevant test data, which is available upon request, to verify these declarations.
