Type 84
Type 84 is operating in the L-Band stationary surveillance radar. The transmitter used a magnetron. The main transmitter was located in a single-storied building above which the antenna was mounted.
The antenna was designed as two 60' × 21' 8" elliptical parabolic antennas placed back-to-back, one as primary radar and the other as IFF/secondary radar system. The primary radar antenna generated a stacked-beam cosecant squared antenna pattern with 8 horn radiators. However, the IFF system originally intended for this antenna was never installed. More modern systems with much smaller antennas were installed, either as a horizontal beacon below the horn radiators or as a parabolic reflector antenna above the main antenna.
