Use this antenna to listen to frequencies below the AM broadcast band.

Directional to help reduce interference when 2 stations from different directions are on the same channel.

Ideal for lightning detection applications in the range of 300 KHz - 530 KHz, this frequency range is filled with continuous static when severe thunderstorms approach.

Weather-proof plastic case.

Binding post connections.

We monitored WWVB on 60 KHz and also placed a solar cell outdoors during the eclipse on August 21, 2017 and got these results here by using a computer and a data logger. This is the type of research that can be done with antennas in this frequency range. We used a 22 inch long experimental version of the above antenna. We were able to see the effect the eclipse had on the propagation of LF radio signals. The signal strength increased near the time of maximum coverage. Here we saw about 75 percent of the sun covered, it was a partial eclipse for us. As the moon blocked the sunlight the voltage on the solarcell --decreased-- and the signal strength at 60 KHz --increased-- (We inverted the data so they would fit together in the chart above).

Works with all types of Long Wave Radios
Greatly boost reception! Simply tune the antenna and place the radio nearby for signal transfer to the radio's built-in barcore antenna element.

Bring back receiving power to your antique Long Wave radios! No wire connection or modification needed, simply place the radio near the tuned antenna for greatly increased signal strength. No batteries needed. The tuned antenna captures the radio waves and transfers them to your radio's built-in barcore antenna.

Simply place the radio near the antenna, adjust variable capacitor to tune in station for a great boost in reception strength.


You can also match and tune a random long wire antenna to your radio's 50-ohm or 300 ohm input.

For 50 ohm match wrap 2 or 3 turns around the tuned up antenna. For 300 ohm match wind 8 or 9 turns around the center of the tuned antenna.
