1/4 wave for 20 meters
1/4 wave for 20 meters
I'm taking my SDR camping for a couple weeks. Thinking that 20 meter band is most active, would I want about a 17' wire for 1/4 wave on that band?

Seventeen feet is about right, but remember you'll need an earth/gnd.

Would 1/2 wave be better? And, if I string it horzontal I don’t need a ground?

Half waves are high impedance feed so you can get away with no ground. If your RX has a Hi-z antenna port it will match quite well.
