No sir, your radio already knows that trick. It will feel that it is being
cheated by you using speaker wire and will refuse to send RF out the antenna
jack. (I'm just kidding.) :-)

But seriously it should work just fine. Treat it as insulated 18 gauge wire.
I did use Radio Shack Flat copper Mega Speaker Cable as Ground Radials - I
zipped them in half and each package made 2 radial wires.

Anyone have experience making a dipole from 18 gauge speaker wire? I
have a whole lot of it lying around the house, and was wondering if I
could put it to some good use.

I dont know about speaker wire but lamp cord works perfectly.you can even use it for feedline (approx 75 ohms). It will last 20plus years even in severe weather. In fact I am transmitting on 7120 on it right now. I cant remember when I hung it but I have lived here since 1986. Swr measured two hours ago is 1.2to1. It is 40m inverted V . This one is fed with coax which was kinda dumb since lamp cord is already balanced line.
