The Loop ATU consists of a capacitive matching network 3 capacitors and a toroidal 4:1 balun. The balun is made using 18 bifilar-wound turns on a 58 mm
La bande 137 kHz
For 137 kHz the coil has about 200 turns of enameled wire
L.F. On-the-air
With UK amateurs having had access to 136kHz for several years, a lot of experience has been gained matching transmitters to a variety of LF antennas
LF Tuning Meter for the 136kHz Band
When adjusting the tuning and matching components of an LF antenna, it is extremely useful, if not essential, to havesome way of indicating the impedance mismatch at the antenna feed point
