Portable Dipole 40 30 17 m band
Wire dipole antenna that works on 40 30 and 17 meters band
Wire trap for 12m WARC band
Le trappole per cavi sono economiche, facili da assemblare in modo riproducibile, ma possono essere fragili meccanicamente facilmente deformabili per operazioni permanenti, su dipoli, V invertiti ecc.
