The correlation results for the Tx feed assembly were subsequently used to update the spacecraft (S/C) L-Band antenna model. The updated S/C model temperature results for both the Tx and receive (Rx) feed assemblies were found to be 2°C to 3° C more benign that the original S/C model results. ...Therefore, the through conductance testing and correlation results demonstrate the validity of using the mathematical model developed for the S/C L-Band antenna thermal analysis.

The efficiency of several Microstrip (Patch) antennas with varying substrate heights etched on a substrate material with a relatively high dielectric constant was calculated from gain measurement data.

The discharge currents that are big enough to make any noise, or visible flashes, or pitting or burning marks on the metal skin of the aircraft are external long discharges that an aircraft flying under thunderstorm conditions may intercept. ...Summaries of airline experiences are given from which it is seen that antennas frequently intercept discharges; a current surge conducted along the antenna lead-in frequently damages radio equipment and in some cases has resulted in fires. ...FOREWORD The majority of thunderstorm electrical discharges involving aircraft are in the “Upper-reaches” of a lightning discharge channel where currents tend to be lower than for the lightning we know near the ground: Therefore, the term “Static-discharge”, which many pilots use when the discharge does not seem violent enough to warrant the term “Lightning” may logically be used as a more general term covering all thunderstorm electrical discharges.
