It's not just a dipole. The helical coils give it a much longer effective length than a straight wire.
Some preppers are into Slinky antennas. Compact in storage, easy to set up, reusable.
You're way better off having a proper dipole outdoors if you can do so.
what i like bout the slinky, is the quick set, and strike down.
i had recalled radio operators in vietnam kludgeing these up in the bush, after getting a couple slinkys in the mail, so i thought it was worth a cycle.
