End-Fed Half-Wave Antenna & Tuner
The radiator itself is simply a half-wave long piece of wire. I used an unzipped length of zip cord, a full free-space half wave length about 41.6 metres

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
