The higher the frequency, the shorter the antenna and vice versa. A basic formula for a dipole antenna (not an L antenna) would be to divide your operating frequency in MHz (e.g. 15 Mhz) into 468.

For example, the Radio Marti shortwave broadcasting station's antenna will vibrate at a frequency of 11.930 MHz (11,930,000 times per second). That radio station broadcasts in Spanish from Miami, Florida.To bias the FET properly (make the gate "negative" with respect to the source (or cathode) and thus set the current through the FET to the right level), it is necessary to have a bias network between the source and ground. Biasing is accomplished by simply using a 10K resistor and a bypass 0.001 MFD capacitor.Circuit Working. The short wave radio receiver could also be used in oscillating mode by reducing the effect of oscillations caused by unwanted coupling to about 100 Hz. The oscillating mode may provide the owner various product-detector reception modes, namely CW, RTTY and SSB. If a frequency counter is added, this feature can be more pronounced.
