IMPROVEMENT TO DOPPLER VOR SIDEBAND ANTENNA MONITOR, TYPE FA-8142

An investigation was accomplished on a Doppler very high frequency omnidirectional radio range (DVOR) Sideband Antenna Monitor to determine methods of eliminating the possibly unreliable operation when an antenna fault occurs. Minor modifications were made in the monitor to improve adjustment. Tests were accomplished in the Doppler No. 2 site at the National Aviation Facilities Experimental Center (NAFEC). Included in the investigation was the operation of the monitor with a slotted cylinder antenna. The test results indicate that the most reliable monitor operation was obtained with the modified monitor using a slotted-cylinder antenna coaxially located above the carrier antenna. (Author)
