Experimental 136kHz Vertical Antenna at
Vertical design progress was rather slow because of other commitments, but by the autumn it was complete and I was able to have some QSO

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
AMRAD Low Frequency Web Page
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!
