This paper will describe the field test program undertaken by RCA Americom to establish the EIRP of its Fl Spacecraft now in orbit. This satellite is used primarily for cable television program distribution. The study was performed as a service to the industry in order to provide actual EIRP measurements as opposed to calculated predictions. The results of that exercise will be presented and suggestions for prudent system designs for users of the Satcom Spacecraft will be put forth. This paper will also address the design of the Americom F3 Spacecraft to be launched in the fourth quarter of 1979. Enhancements incorporated for the benefits of the cable television community will be presented and projected contours will be shown. RCA Americom plans to provide actual EIRP measurement results for fuTure satellites used by this industry.
