About this file
This document is a technical specification table for Peak On-Axis Co-Pol Equivalent Spectral Density (ESD) for an Inmarsat Full-Band Configuration, with document reference number 1006010-122. The table provides detailed gain and elevation measurements at various skew angles from 0 to 90 degrees, specifically for a frequency of 29.5 GHz. The data represents peak antenna ESD limits relative to FCC 25.218 regulations, excluding Non-Geostationary Satellite Orbit (NGSO) Cross-Geo considerations, and includes radome losses. The gain measurements are referenced to the Coax Input of the Transmit Line Replaceable Unit (TX LRU) and averaged over azimuth. Shaded areas in the table indicate satellite-user longitudinal offset angles exceeding 40 degrees, which may have different performance characteristics.
