In a transmittingantenna, it comes from the transmitter. As the wave continues through the rest of its cycle, theantennadischarges and charges in the opposite polarity. Thus, the rest of thecircuitconnected to a receivingantenna“sees” an oscillating voltage corresponding to the original wave.
Although thecircuitis very simple, it functions very well without externalantennaor ground connection. The transistor T1 works as a feedback regulated HF-amplifier and function as demodulator at the same time. The sensitivity of the receiver is dependent on the amount of feedback and can be adjusted by P1. Transistor radiocircuitschematic

Apr 02, 2018·AntennaTuners are an impedance matchcircuit.AntennaTuners match the impedance of yourantennasystem to the impedance of your transceiver.AntennaTuners, the components in them, and yourantennasystem are all composed of reactive elements. Since reactance changes with frequency, a match is only perfect at one frequency.
Apr 07, 2018· Good point, I actually missed the 144-220 MHz marking (not so easy to see). Still if it only monitors "forward" and not "SWR," tuning it is a bit arbitrary unless it is actually monitoring line current (maybe it is, would be interesting to see thecircuit), and when you're all done you still don't know anything about the match or the forward power.
A resonant, full wavelengthantennais much longer than 60 feet. In fact, a full-length VLFantennawould be about 60 MILES long! A smallantennaproduces very little signal current for reception, however, a high gain, high impedance amplifier canmakeup for the difference.
