Broadbanding half square antenna for 80mt
Half-square antenna is by naturerelatively narrow band.1On80 meters, for example, an SWR be-low 2:1 can be achieved anywhere in theband, but only over a relatively small range 60 to 100 kHz

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
