Low-cost ½ λ Dipole for HF QRP rigs

[vu2nan]

This is the antenna I strung up ages ago, when I had hombrewed my vacuum tube transmitter and couldn't wait till I had acquired some coax!

I like it Nandu. Simple,light and cheap!

another secret tip: when you use twin lead electricity appliance wire (the wire which plugs into your 110/220 V sockets), you impedance will be near 50 Ohms symmetric. You only need a 1:1 balun at the end of the wire.

The impedance on the wire you are speaking of would calculate out to around 105 ohms, but still only a 2:1 swr thus a 2:1 balun or transformer would be needed.

Thanks, OM Dave!

Hi OM Joop & OM Richard,

No problem since I've used the antenna with rigs having pi tank output.
