Splet26. mar. 2024 · This is my first DIY antenna, 120 turns of 28 AWG enameled copper wire, on a 135 x 10mm ferrite bar. The twisted antenna wires get plugged in to external AM antenna jack on stereo. Without the variable capacitor (141.6 pF yellow lead, black lead ground to copper baseboard water pipe, red lead 59.2 pF), I barely get signal. SpletThe Quantum QX Loop v2.0 is a 7.5" ferrite rod antenna that covers 530-1800 kHz. It features a double-balanced JFET/JFET amp, a tilting loophead, and Q-multiplication. The Quantum QX Loop v2.0 replaces the original QX Loop and QX Pro Loop and also accepts loopheads for the LW and Tropical SW bands. It has an external antenna connector so …

Splet03. nov. 2024 · I also started making a wider band SW ferrite rod antenna, same rods but different windings. Right now the highest tunable freq is about 4MHz and with a 365pf variable you use several fixed caps switched in and out to take it down to the AM BCB. I can also switch in fixed caps and take my AM BCB version down to the VLF range.

SpletPrimarily, a ferrite rod antenna is used to receive lower frequency signals between 50hz to 50khz. It operates as transmitting antennas for applications that are suitable with low levels of power & low efficiency. If the power levels are high, then the ferrite rod may incur heat dissipation issues. Splet02. dec. 2024 · 1.
