Table of wavelengths per band
The tables below give for each amateur band and a few other frequencies the full wavelength (300 / f), the half-wave, and the quarter-wavelength

Largo de los Cables Coaxiles
We can calculate the length of the coaxial cable that we are going to use. It is long, it is determined in a quarter wave, this is due to the fact that the impedance of the antenna must be adjusted to the cable to be used and the radio
Measurements on Balanced Lines
Over the years, distortion in amplifiers and other electronic devices has been measured by many different techniques
Meglio FSK o AFSK
Nell'ambito delle trasmissioni RTTY con le schede audio, e' possibile trasmettere in modalita' FSK o AFSK
Grounding and Receiver Noise
A good grounding of the radio, and a mains filter, can eliminate many problems, such as radio frequency interference
Passive Antennas
The shortwave frequencies are generally considered to be the portion of the radio spectrum between 1.7 MHz and 30 MHz
