End Fed Halfwave and Tuner For 80-160
I planned to set up portable and lift the 123-foot wire with some helium balloons and operate in the QRP category
HF/6M Antenna Tuner Preselector and Antenna Switcher, ON6MU
Frequency range: 2Mc...52Mc, 180m band depending on the mismatch of the antenna used and/or maximum inductance. Experimenting with the coils can be desirable
Hf remote antenna unner unit
Consiglio un cavo coassiale per il collegamento del servo fra box di controllo e accordatore
HF/VHF Portable Mini Tuner
Variable capacitor of at least 300pF or better 500 pF,frequency range depending on the coil min & max inductance 160m...6m

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
