Coupled Tuner LCT
The Link Coupled Tuner, or LCT, inductively couple an RF signal from the Transceiver to the Antenna System, and also in reverse
Controlled 80m antenna tuner
I decided that what was needed was some means of controlling the capacitor from the operating position, and so I developed a means to accomplish this
De L-Tuner
The L-tuner consists of only two components: a coil and a capacitor
Halfwave wire lengths 12 thru 40 meters
This project was the result. I ordered the variable capacitors from Emtech, they are the type used in the Emtech ZM-2 tuner. They are dual gang polyvaricons that are 266 pf per section
