Constructing a LowFER Antenna
- Getting on the air with a LowFER station is more complicated than getting on the ham bands since commercial equipment isn't available and construction is involved

Antenna 136KHz Links →
Antennas for 136kHz
The gain of an antenna is always given relative to a reference antenna. Most common references are the 1/2 wave dipole and the isotropic radiator

LF stands for Low Frequency, that portion of the RF spectrum extending from 30 through 300 kHz. In Europe, where there are numerous broadcast transmitters between 150 and 250 kHz
Build a 136kHz TX
The diagram for the portable TX is below. It is built on the KISS principle so there's not much to it but it is capable of producing nearly 400W with the engine running!
