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

23cm Yagi Antenna building Finished antenna at 1275 MHz SWR under 1:1.5 at resonant frequency
50 MHz preamp Gain 26dB with the BFG135 Preamps for 144 and 430 MHz, for 50 MHz, the BFG135a is a cheap transistor and in my view rather strong. It is not easily damaged by static discharge or RF power. FG connection
