OTC Satellite Earth Station Carnarvon

The ‘sugar scoop’ antenna became operational on 29 October 1966 when Intelsat-2A, the first of the three satellites launched, gave OTC and the ABC a brief chance to test satellite TV communications as the satellite drifted to ignominious failure over the Indian Ocean.

The Junliangcheng Antenna Tower (军粮城发信天线塔)in Dongli has the more powerful (10 kW) long-distance MF/HF transmitters.

Radiation pattern

These axially symmetric antennas have radiation patterns with a similar symmetry, called omnidirectional patterns; they radiate equal power in all directions perpendicular to the antenna, with the power varying only with the angle to the axis, dropping off to zero on the antenna's axis.
