WebThe roller coil. The output capacitor. The split-stator input capacitor. These tuners were used by the military during the Second World War. This unit is probably capable of power levels up to 5,000 watts. Schematic diagram of “The Ultimate Transmatch,” designed by Lew McCoy, W1ICP. WebThe efficiency of the tuner is good, because it can be considered as an auto transformer with inductive and capacitive taps on the coil. Originally the design was a three knobs …

L-C Tuner - Coutant

WebThe advantage with open wire is that the antenna can be tuned from 3500 to 3800 kHz and from 1810 to 1900+ kHz. Open wire tuner A remote open wire tuner was needed as the … WebThis capacitance must be tuned out if what is adequate drive on 3.5MHz is to produce full output on the higher-frequency bands. PAOFRI does this with a dual-resonant circuit (L3 and ganged tuning capacitors) similar to the well-known E-Z-Match antenna tuner; it covers 3.5-29MHz without switching. WebAfter reading a lot of information on the internet about the LL tuner, it soon became clear to me that this tuner had to be special. Meanwhile i also studied on the principle of tuners and became enthusiastic about the concept of the S match from PA0FRI. I was happy to learn that Kees adapted this principle and also builds the LL-S match now. react building tool
