Mini Antennas for 20 Hz to 350 KHz

Miniature Very Low Frequency Antenna

ANTM1. This directional VLF antenna can be tuned from 3 KHz to 33 KHz with an external capacitor value of 0.1 uF to 300 pF. @ 300 pF tunes to @ 33 KHz. 0.1 uF tunes to @ 3.1 KHz.

Weather proof sealed. 6.5 inch wire leads. 6.5 inch long CPVC plastic case. Great for use in series resonant VLF transmitters or VLF receivers. 1 watt max.

ANTM1 is $ 30.00 + s/h.

DC - 30 KHz Wideband Instrumentation Amplifier for use with these antennas.


Useful as antennas and in tuned frequency selection circuits, filters, sensors.

DC - 30 KHz Wideband Instrumentation Amplifier for use with these antennas.

NOTE: Antennas are 4 inches long. ELF antennas are larger diameter than unit shown in photo.

NOTE: These antennas are bi-directional having a 'figure 8' pattern.

NOTE: Works either series resonant (low z) or parallel resonant (high z). External capacitor is user supplied.

NOTE: Table above shows tuned frequency in KHz or Hz when external capacitor value is used in parallel or series with the antenna.

NOTE: GREEN color in table indicates antenna has best performance at this frequency and above.

NOTE: PINK color in table indicates antenna has wider bandwidth and lower performance at this frequency and below.

NOTE: SRF is the highest possible frequency the antenna can operate at, but it is recommended operating below this value using the minimuim and maximum capacitor values shown.

NOTE: Table shows user-supplied capacitor values needed to tune the antennas to frequencies shown.

NOTE: Frequency Tolerance Specifications: +/- 20 %.

NOTE: The ( - ) lines in the table indicate that the antenna is not for use with that capacitor value.

NOTE: Highest and lowest capacitor values and highest and lowest frequency working ranges are indicated in the table.
