Double Twin Quad Antenna Project for 70cm
The Double Twin Quad Antenna for the two-meter band we were very surprised, if not deeply impressed, by its apparent performance
Dual band colinial 144-430
97 cm RG8U stretch VHF, 32 cm RG8U stretch UHF, 16 cm stretch RG8U UHF
Gamma match
The layot of the gamma-match,mnusthe capacitor, is one-half of a T
Embedded GSM antenna
Embedded GSM antennas Lambda/4 the red coloured part of the picture view is the part of antenna that will radiate at the lower band GSM 850/ 900MHz. A+B+C+D = 79 mm
Easy antenna dual band VHF-UHF
Questa antenna, concepita con l'aiuto di Yagi-Calculator, un piccolo programma molto pratico

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
