It has a moving rather than omnidirectional antenna. A magnetometer was attached to the top of the mast below the omnidirectional antenna. The magnetometer was attached to the top of the mast below the omnidirectional antenna. The 200-line mode transmitted over an omnidirectional antenna and scanned one frame every 61.8 seconds. The 200-line mode transmitted over an omnidirectional antenna and scanned one frame each 61.8 seconds. A completely uniform omnidirectional antenna is not physically possible. Each antenna in a DVOR uses an omnidirectional antenna. This was supplemented by a metre wavelength range transmitter through the omnidirectional antenna. To combat this, an omnidirectional antenna is used for a comparison signal. Omnidirectional antenna surveillance coverage of the TLS extends to 60 nautical miles. A cylindrical quasi omnidirectional antenna was seated on top of the conical tower. Some cellular repeater systems can also include an omnidirectional antenna for rebroadcasting the signal indoors.
