Reducing noise to your antenna
You must have a good install to eliminate the most common problems
Rhombic antenna for shortwave
The rhombic antenna is a diamond-shaped antenna, suspended between 4 masts
RX con antenna a quadro con ECL82
Si tratta di un ricevitore a reazione, basato su una variante del circuito Hartley
Shielded-Loop Receiving Antenna
Shielded-Loop antennas have some nice properties that make them desirable as portable receiving antennas
SWL - Shortwave Listening
SWL or shortwave listening is the reception of public broadcast or amateur radio ham stations in the frequency range 1.8 to 30 MHz

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
Qrm Eliminetor The principle is based on the fact that the interfering signal from the main antenna coming from the local interfering signal is phase-shifted by means of an auxiliary antenna so superimposed that eliminate the interference
