Results of UHF Mutual Enviroment Test Program at Rome Air Developement Center

This report is a summary of UHF mutual interference tests performed at the Rome Air Development Center, Rome, New York. Initial tests were performed in the Laboratory and at the Verona Test Site of RADC by RADC engineers to obtain interference characteristics and operational parameters of the UHF communications equipment. The results of these tests, which are presented in Phase A, were submitted to Bell Telephone Laboratory engineers at Whippany, N. J. for use in their study program to obtain a UHF Frequency Allocation Plan for SAGE. The field test program which followed was established to check the compatibility of the BTL UHF frequency families which resulted from the aforementioned study. Specifically, a determination was made of the interfering effects which occur when combinations of single channel UHF transmitters and receivers are operated simultaneously in close frequency and physical association. This work was performed at the Verona Test Site of RADC by Collins Radio Company under Contract AF 30
