Abstract:

Due to the unique construction of RG-115AU, a more temperature stable cable is obtained. Short term applications to 800F are possible due to the taped construction allowing for Teflon expansion. At 600F, RG-117U becomes difficult to work with because of the longitudinal thermal expansion of the Teflon dielectric. However, it probably can carry more power at that temperature than any other braided cable that is commercially available. Connectors employed with coaxial cables at the high powers and environments concerned here must of necessity be of the solderless type due to inner conductor heating. For life-index purposes, the present conservative power derating factor of 1VSWR seems to be rather high, especially for VSWRs as low as 21. System VSWRs of the latter magnitude may not materially contribute to short term life-index power ratings. Author
