Dec 3, 2020 · How to Build a Simple Linear-Loaded Dipole for Low-Noise Shortwave Radio Listening. 13 Replies. Many thanks to SWLing Post contributor and RX antenna guru, Grayhat, for another excellent guest post focusing on compact, low-profile urban antennas: Any antenna that is less than 1/2 wavelength long and less than 1/2 wavelength high will start to loose efficiency when shortened or lowered. (1/4 wave verticals must also be at least 1/4 wavelength long and have an almost perfect ground plane). So for HF frequencies if you want to go a similar route you should look into magnetic loop antennas.The antenna covers 5 MHz through 14 MHz. Here are some general comments regarding this DIY antenna.

In fact, an ATU will pre-select the range of frequencies you want to hear and by default reject the rest. This can improve signal-to-noise ratio, so improving your perception of the signal you want to hear. A modern radio passes a band of frequencies (band pass tuning or filtering) for processing. In that band, signals large and small appear.Dec 9, 2022 · This entry was posted in Guest Posts, Music, News, Shortwave Radio, What's On Shortwave and tagged DJ Frederick Moe, Fastradioburst23, Imaginary Stations, The DIY Ethic, WDIY, Wough Science Saucepan Radio, WRMI on December 9, 2022 by Fastradioburst23.

If using PVC ask for the Ultra Violet (UVA) resistant type as it will last longer outdoors. Your idea of using a vertical for an ARES (or RACES) antenna is bad. You would be much better off with a dipole or doublet at least 22 feet high, but preferably around 30-35 feet high.Shortwave radios operate on a frequency range between 3,000 and 30,000 kHz. Shortwave bands have frequencies ranging between 3 and 30 MHz (3000-30,000 kHz). They feature a relatively lower wavelength (hence high frequency) than conventional radio communication waves. This is why they’re called shortwave radio waves.Any antenna that is less than 1/2 wavelength long and less than 1/2 wavelength high will start to loose efficiency when shortened or lowered.

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 ...Each time you double the OD of the wire or tubing, you can expect about a 3db increase in efficiency.
