End Feed Half Wave verticale
Per radiatore dell'EFHWA e' utilizzato un filo per impianti elettrici da 1.5 mm quadri tagliato esattamente a 9.84 mt

Si puo' montare praticamente dappertutto,in tutti i casi possibili della nostraattivita', rende abbastanza bene ed e' facile ed economica da costruire
Four square phased verticals
The four phased verticals system . It is primarily intendend to be used on the lower bands 160m, 80m, 40m
GP for 40, 80 and 160 meters
As mast an 18 meter glass fiber mast of Spiderbeam,the system is sized to have the radiator and coil resonance at 160 meters
