By using previously developed techniques for digitally modeling terrain, an antenna site was determined which would provide Category II performance using the compensated waveguide antenna. The effects of reflections from the runway embankment and irregularities of the terrain were minimized by a combination of compensation, coning and antenna placement. Pattern measurements and antenna feed measurements were made at the Westinghouse Antenna Range and these provided information necessary for the installation and tuning of the antenna at Buffalo. Once installed, flight test information required small changes to the antenna feed system in order to meet Category II requirements. Initially, the monitor system exhibited some instability but this was solved by using new loops and re-configuring the monitor channels. Author
