Semplice dipolo rotativo per i 12m e 17m
Un dipolo per i 17mt rotativo con un Balun 1:1
Dipolo accorciato per 40 80m
La sintonizzazione dovrebbe iniziare sulla sezione 40m con una distanza di 10,5 m
The FD4 (FD3) windom antenna
The 4-band Fritzel model FD4 is a special version of a Windom antenna. It is a half-wave long on the lowest frequency
T2FD squashed rhombic
Denominata anche T2FD Terminated Two Wire Folded Dipole Antenna, si tratta essenzialmente di un dipolo ripiegato
The HF Antenna
The end fed wire antenna lends itself readily to QRP and portable operation.The Tuning capacitor in the AMU can be a 365 - 500pF

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
Interface-for-digital-broadcasts-with-integrated-audio 4-port HUB, with a TUSB2046. With port 1 of the HUB we drive the FT232RL; with port 2 the PCM2904, furthermore, we decided to leave ports 3 and 4 free
