Dickerdipol antenna multibands with balun
The 5 radiating wires are spread to 1.2 m. with un balun 1:4
Dipolo acortado
The calculation of the linear load is made by adding 30% to 30% removed from the irradiator, the dimensions being as follows, Total length of the irradiator: 5, 51 meters Length of each linear load: 1.54 meters
Dipolo HF 80m - 60m - 30m
Ho deciso di costruire un dipolo che mi permettesse di operare sulle gamme 80m-60m e 30m
G5RV antenna 40/10 & 80m - 40-10m
I bracci terminali possono essere istallati o paralleli al terreno oppure a v invertita
Multiband wire antenna

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
