Diy shortwave radio
The SWLing Post. 13. I’m plotting to write a more in-depth article about antennas in the coming months, but it will focus on external antennas and methods of mounting them. When you have no means of mounting an antenna outdoors, in my opinion, your best options are the ones mentioned above.Pick a piece of wood/plastic or other insulating material, cut it to size (refer to marking and to balun size) and drill four holes matching the one found on the balun board. Slide four screws through the holes and lock them with nuts, the screws should be long enough to extrude for some mm. Now insert the balun in the screws using the holes ...

When the reactance (AC resistance) of capacitor C2 is the same as the reactance of the coil L1, resonance occurs at the frequency f=1/2π√ (LC). For example, with L1 equal to 300 uH and C2 equal to 100 pF: F = 1/2π√ ( (0.0003 H)* (0.000000000001 F)) = 919kHz.

For the specifics of winding your inductor, it is best to rearrange formula 1 to find the value of L for a given capacitor value and a given target frequency: L = ( 1 (2πf))2 C−1 (2) (2) L = ( 1 ( 2 π f)) 2 C − 1. So for your shortwave example, if your capacitor is set to 500 pF (500 x 10 -12 farads) and you wish to receive a frequency of ...Place the capacitor on the mount. Ensure that the movable paper-foil tube side is facing outward so that you can easily adjust the size (volume) of the capacitor.
