Ever wanted to know more on the RX & TX characteristics of your CB Radio whilst in a QSO with a DX contact? Have you considered the options of using Tablet or PC’s to display the AUDIO and RF spectrum across 27 Mhz with a simple $20 SDR USB dongle?
In layman’s terms a DDRR is just a short vertical monopole (vertical post) attached to a transmission line tuned by a reactance (ring plus vacuum capacitor). The reactance of the capacitor is transformed by the transmission line and will under specific conditions (length, value of the capacitor, etc.) make the vertical post resonant. Slight variations of the capacitor will lengthen or make the transmission line “shorter” and allow tuning of the antenna on a certain range.
