A low cost fishing pole vertical antenna
On 7 and 10 MHz the performance of a ground mounted vertical is good compared to a typical dipole at 10 Metres above ground
Alte prestazione sulle bande basse
Sulle bande piu basse l'utilizzo di verticali poste in prossimita' del suolo e molto vantaggioso
Antena vertical para 10, 15 Y 20 Mt
Two coils that we will mount on PVC pipes, 75 mm. in diameter and about 12 cm in length, winding together 36 turns of 1.5 mm diameter varnished wire
