摘要： An underground transmitter can be configured for use with a drill head and configured for wireless communication. The underground transmitter can include a control circuitry and a multi-coil antenna assembly. The control circuitry is configured for transmitting data associated with an operation of the drill head. The multi-core antenna can include an antenna core and a plurality of distinct wire coils. The plurality of distinct wire coils can be positioned proximate (e.g., around) the antenna core, with the distinct wire coils each having a different inductance associated therewith and thereby capable of transmitting in a separate frequency range. The control circuitry can be selectably coupled with the distinct wire coils to control which of the distinct wire coils are activated and thereby generating data signals at a given time.
