Yagi due progetti per gli 11m
Yagi 4 elements for 27 MHz
Dipolo filare con balun per 27 mHz
dipole centering on channel 20 CB or 27.205 mHz and using a 4 mm copper braid, from the above mentioned formula we get 150 x 0.965 / 27.205 = 5.32 meters
Hentenna freq 27.500
Hentanna is that if it is mounted horizontally, the resulting RF field is vertically polarized and vice versa
Antenna Stealth Vertical Dipole

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
