Abstract:In recent years,due to the rapid growth of air traffic control business and the increasing number of control sectors, the VHF equipment and frequency of ground to air communications are increasing. The electromagnetic environment is deteriorating,and many inter-system interference are gradually emerging. This paper puts forward some suggestions for the construction and maintenance of VHF stations through a survey of intermodulation interference.

Keyword:very high frequency;antenna;intermodulation interference
